Larch-4 testing, can also 'livify' existing Arch installation

I've uploaded a testing repository for larch-4 to:
ftp://archie.dotsrc.org/projects/archie/larch/testing
It has some added features which need testing - especially with USB, which is difficult for me to test because my computers are rather old and don't support USB boot.
It should now be possible to adjust the session-saving behaviour without modifying the larch scripts - additional scripts (hooks / event-handlers, call them what you will ...) can be placed in a 'scripts' folder in the root directory of the boot device (using the profile mechanism) to adjust loading and saving of overlay files. Initial description (sorry, it's still rather sketchy) in the session-saving doc page.
The home directory is now a separate sqf (not overlayed).
Added options to mklarch to build a CD/USB-stick from an existing Arch installation. This can be done, for example, from a live CD (using the -x option) or even from the system itself while it is running (option -X). This could be rather dangerous - don't do it on your main installation. I've tried it out - without obvious damage - on a test installation, and it looked quite promising, but be careful.
Added option -r to mklarch to ensure regeneration of base and system sqfs when 'reusing' an installation (with options -b, -x, -X).
Changed the place where the live CD is built (default /home/larchroot) and the structure within this folder. The installation is now made directly to this location and the building is done in subfolder .larch, where the final iso also lands.
To use it, just copy the larch-setup.sh script to an empty folder and run it (as before). Then you have the new mklarch set up and ready to go.
Feedback welcome.

Hi gradgrind, this tool is really what I'm looking for. I have 3 partitions: /dev/sda1 -> swap; /dev/sda2 -> reiserfs (partition where my system is installed); /dev/sda3 -> reiserfs (partition where I'm running mklarch script). I want to try larch but I have a few questions.
1) To create a LiveCD from my current arch setup I only need to  run
./mklarch -X
If you're running the system you want to save, yes. But from your description it sounds like you're doing something else. Do I understand correctly that you have some other system unrelated to sda2 on sda3 and you want to run mklarch from sda3? And what you want to livify is sda2? Then you need to do something like:
# mount -o dev,exec /dev/sda2 /mnt/sda2
# ./mklarch -x /mnt/sda2
Note the small 'x'.
spookykid wrote:2) Is it possible to add gensplash to larch?
Sorry, I have no idea about gensplash. If it's supported by Arch then it should work with larch too, but it's not something in which I have any interest.
spookykid wrote:3) For what I've read about larch I can have a system installed with 4 GB and that will fit on a 700 MB CD?
I hope I didn't write that. You might need that much free space to build a 700MB CD, but a more accurate estimate of what fits would be about 2GB. If you want more you'll need correspondingly more free space and a DVD or a large USB-stick.
spookykid wrote:4) Larch will only go for my /dev/sda2 partition (where i have my system) or will it add all available partitions to the live image?
It just packs up what it finds at the mount point, so if you've got other stuff mounted within the system (I guess in your case you probably haven't) don't be surprised if it tries to pack that up too. I think (I hope!) it ignores stuff mounted within /mnt and /media, but I'd have to look at the code again to be sure. For people who have /home or /var or whatever on separate partitions it is necessary to mount these before running mklarch.
If you use 'mklarch -X' (big 'X') to build a live CD from the currently running system, all the mounts should be ok anyway, but I think that in general building from a separate system, as you seem to want to do might be slightly safer.
In any case, please back up anything important before running mklarch - just in case! It runs as root and could do all sorts of nasty things. I don't think it will, but don't blame me if it feeds your grandmother to the ravenous bugblatter beast of Traal

  • Install windows 8 on an existing arch installation

    Hi Friends, I don't know if this is the correct place to ask but after many hours of googling, I am asking this question. I had two operating systems installed on my computer which I dual booted with grub: Windows 7 and Arch linux (Archlinux is still intact on my computer). Windows 7 got corrupted with virus and now it has become unusable. so, I decided to install Windows 8 in place of it. so, Friends, can Windows 8 be installed keeping the arch installtion safe ? Has anyone tried this method in which is linux is pre-installed and you have to install a new version of windows. I dont want to lose my arch linux installtion. If you want more information about my system partitions , I am willing to give it to you.Please Help.
    I searched on Internet but found only the installation methods in which windows is installed first and then linux is installed. Many thanks.

    Thanks Friends for your Replies.
    But I think Somewhere I read that Windows Detects the linux partitions as unusable and formats them too. so, can anyone give me a confirmation for this?
    My Partitions are as follows:
    /dev/sda : ( 500 GB Hard-disk)
      1) /dev/sda1 : System Reserved ( Windows 7 ) (100 Mb) (ntfs)
      2) /dev/sda2 : Windows 7 ( Actual windows 7 installations) (362 Gb) (ntfs)
      3) /dev/sda3 : Arch-Root ( actual arch linux installation) ( 50 Gb) (ext4)
      4) /dev/sda4 : Extended partition in which the below partitions are included
           /dev/sda5: Arch-Home ( seperate home partition ) ( 100 Gb) (ext4)
           /dev/sda6: Swap Space ( 2 Gb ) (swap)
           /dev/sda7: Arch-Boot ( grub is installed on this partition) ( 500 Mb) (ext4)
      Please can anyone give me re-assurance for what I want to do. Cause Installing another operating system is a big step unless and until you unterstand follow it clearly.
    Also, will I be able to boot Arch-linux from win 8 boot loader conidering my partition set-up ( To be specific , I want the Win 8 BootLoader's Mouse and touch funcionality)
    Please Guide me step by step.Many thanks.

  • Suggestion to arch installer...

    I'm a newbie to arch. I just moved debian/ubuntu to arch, but I'm not a distro hopper. I'm now fascinated to arch, but I'm also frustrated to arch installation system.
    I don't care installing os by console(ncurses). It's quite simple and efficient. I often installed debian/ubuntu in this way previously.
    My suggestion is
    1. partitioning
      after cfdisk and we go through /arch/setup. Yes! "kiss" principle is important. Everything should be simple. but, we might lose "integrity" in the view of installation. cfdisk - partitioning (format stuff) - editing /etc/fstab the separated steps also make sense to me. However, in my opinion, will it be better that they merged into one step? I'm a newbie That's why I didn't find the way to keep(preserve) the previous partition. Whenever I tried to mount ie. "/home" it just formats. I solved this problem to skip the step, not to mount, and I edited /etc/fstab at the end.
    2. choosing packages
      we can choose base/base-dev packages. I love this because it provides the way to build the really minimalistic system. About 100 packages, I think most of people can't memorize exactly what they are, what they do. Will it be better to show short description like which utilites are installed, which daemon works, what they do... I believe that the user-friendliness during installation doesn't harm the system efficiency or compactness.
    I hope the arch keep this way.. however, a bit kinder or nicer...

    mairoo wrote:Dieter@be, Thank you so much!    It's really helpful. I answered "no" and it really worked what I thought. I'm not good at English cuz my mother tongue is Korean. I hope the feature-request FS#13040 is accepted sooner or later. the way of curses menu during kernel compile could be a good model. Finally, I hope "the menu" could be a bit more /intuitive/ for poor english skilled people like me.
    So, you tried again, you answered 'no' to the 'recreate?' question and this allowed you to choose a mountpoint and it automatically put the needed line in fstab, without overwriting your partition?
    Suggestions for better menu's are welcome also.  There is also a ticket open for a translated installer (i18n or i10n or whatever it's called), but I'm personally not convinced if it's worth it.  It will depend mostly on contributions from other people.

  • Autopopulate archiso from an existing archlinux installation?

    (not entirely sure this is correct forum section for this, but it's at least closely related)
    has anyone created a script to automatically populate archiso with the relevent data extracted from an existing arch installation?
    so you can basically clone your current setup to an iso file, ready for live use as cd or usb.
    or are there scripts that bypass archiso and can independently create a nicely squashfs'd/lzma'd  iso, automatically, from the current installation?
    ... i want a "and-the-monkey-pushes-the-button" solution.

    I was looking for the same, so i made a
    pacman -Q|cut -d " " -f 1 >packages.list
    but to my 'bug' surprise, mkarchiso is unable to locate any pkg i installed from aur.
    Is there a way to tell mkarchiso to use local packages?
    -EDIT-
    I've tried to create .pkgs via bacman and put them in /var/cache/pacman/pkg, but still not avail:
    #> bacman caps
    #> mv caps-0.4.4-1-i686.pkg.tar.gz /var/cache/pacman/pkg/
    #> make all
    error: target not found: caps
    make: *** [root-image] Error 1
    #> pacman -Q caps
    caps 0.4.4-1

  • [Solved] Can't boot into Arch after deleting some partitons

    About 6 months ago I installed Arch on a machine that used to run Ubuntu. Had some trouble at the time getting to boot into Arch but somehow managed. Now eventually decided to delete the old Ubuntu partitons to free up some space using gparted. Arch partition number changed from sda12 to sda6.
    On rebooting after deleting ubuntu partitions with gparted, I got an ubuntu splash screen and a whole lot of ubuntu boot options. Somehow these were all contained in my Arch's /boot/grub/menu.lst. Arch is all on one partition and no separate boot partition (which I had with Ubuntu - maybe I haven't deleted that and this is the problem?). Will need to check that out.
    I can chroot into Arch and did the following -
    grub> find /boot/grub/stage1
    (hd0,5)
    grub> root (hd0,5)
    Filesystem type is ext2fs, partition type 0x83
    grub> setup (hd0)
    Checking if "/boot/grub/stage1" exists... yes
    Checking if "/boot/grub/stage2" exists... yes
    Checking if "/boot/grub/e2fs_stage1_5" exists... yes
    Running "embed /boot/grub/e2fs_stage1_5 (hd0)"... 16 sectors are embedded.
    succeeded
    Running "install /boot/grub/stage1 (hd0) (hd0)1+16 p (hd0,5)/boot/grub/stage2 /boot/grub/menu.lst"... succeed
    ed
    Done.

    I need to post this now and come back from a different machine to note the error messages I am now getting on boot. ...
    Note that when I boot and press esc to get the menu I get the menu.lst I created (in the second quote) above in /dev/sda6, ie the one with the Arch hd and uuid entries - so grub is looking there and finding that menu.lst, but something goes wrong after that.
    OK. Have now booted the machine and after pressing esc and selecting the uuid entry (the same thing happens with the hd entry) I get a whole lot of stuff, but what seems relevant is (typing it out) -
    List of all partitions:
    No filesystem could mount root, tried:
    Kernel panic - not syncing: VS: Unable to mount root fs on unknown-block(0,0)
    Pid: 1, comm: swapper Not tainted 2.6.39-Arch #1
    If anyone can help I'd really appreciate it. This is my MythTV machine so the WAF is about to take a big dive!
    If I could just install grub to the MBR as if this was a new installation of Arch that would be great.
    I am really lost as to what is going on, which I'm sure is evident.
    Thanks a lot

    Hi. Unfortunately that didn't help.
    So next, based on this post https://wiki.archlinux.org/index.php/Ke … el_version I chrooted into Arch and (a) rolled back and (b) reinstalled my kernel but that didn't help either. I suspected it wouldn't because the kernel was working fine before I deleted the partitions in question.
    [2011-08-08 23:32] ==> Image generation successful
    [2011-08-08 23:32] upgraded kernel26 (2.6.39.3-1 -> 2.6.39.3-1)
    I then did a pacman -Suy and the linux package has now replaced kernel26. ( See this wiki entry http://www.archlinux.org/news/changes-t … filenames/). I didn't change anything in menu.lst owing to this and it seems there is no need to. Unfortunately this hasn't helped either - still getting the kernel panic.

    [2011-08-09 00:26] installed linux (3.0.1-1)
    I don't think I've mentioned that my old menu.lst seems to have disappeared and so must have been on one of the partitions that were deleted. I did have 2 Arch installations when I was setting things up months ago and that menu.lst may have been on the other partition but pointing to this partiton's kernel for booting. Presumably that's possible since this partiton is definitely the one I have been using for the last several months (confirmed by log and other files updated in the last few days etc). Even so, I suppose that probably wouldn't be relevant to this issue, since grub is finding the menu.lst on this partition when it boots so it is looking in the intended place now.
    It seems I'm at a bit of a dead end. It seems these kernel panics are usually because there is something wrong with the kernel - which there wasn't with mine (and presumably the kernel in the new linux package is fine) or there is a typo in menu.lst (I can't see one and nobody has pointed one out yet) or menu.lst is pointing to the wrong partition (mine is pointing to the same partition and /boot directory that is found by grub - which is where my boot image is located - so it seems to be correct). I have nevertheless tried editing the menu.lst entry when booting to boot from different partitions but so far that hasn't worked either.
    If anybody has other ideas I'd really appreciate it.
    If not, some suggestions on re-installing would also be appreciated. I have a recent tar archive of the partition, but presumably reinstalling that wouldn't be of much use since it would just put back what is currently there. I guess that I need to format the partition, create a separate boot partition, do a fresh install of Arch into the formatted partition (and with boot in the new boot partition). And then restore my tar backup (excluding the boot directory) into the formatted partition?
    Any assistance greatly appreciated.
    Thanks

  • I have a mid-2010 iMac and just purchased a 2TB TC, can't join existing wireless network with AC standard so attached to iMac via ethernet with TC wifi turned off.  How do i access TC now? not showing up in disk utility or on desktop. working fine with TM

    I have a mid-2010 iMac and just purchased a 2TB TC, I just found out that it can't join existing wireless network with new AC standard so attached to iMac via ethernet with TC's wifi turned off.  How do i access TC now? not showing up in disk utility or on desktop. It is working fine with TM.  My cheeper seagate drives etc kept crashing, so i didnt trust cheeper back up options anymore.  Connected those drives to TM via firewire and could see the drives and access them.
    Also, I didn't want to bridge TC with my new fios router that I paid 100 dollars for, to get N speed and also paying 10 dollars more a month for fast speed.  I heard that bridging slows down everything and then there can be port issues with mail etc.  I connect to the internet via airport only and it is pretty fast. Getting over 50mbs downloads and over 30mbs uploads.  Plus everything in my home it connected to my fios router, airport express for music streaming, two apple tvs, vuezone camer system.  I really didn't want to monkey around too much with my system.  But are there other options to connect the new TC.  Can't find info anywhere for this and called apple who gave me the info above.  after hanging up, i see that i cant access my TC and I am wondering if i would have to reset it to turn wifi on again to make changes to the drive, turn off blinking light  or repair it in disk utility if it should become corrupted.
    For other with similar issues i did solve some other problems: when i connected it to my ethernet port on my iMac wifi stopped working.  Found that I had to turn off the ethernet in the system>network screen, but then TM didn't see the TC so i restarted after changes and then it saw it.
    Now a rant.  I can't believe in this wireless age that Apple would make a product that cant join a wireless net work.  The apple rep said i could return it and look for the previous TC that would join an existing wireless network.  Are we going backwards?
    Thanks!

    Ok... it is getting a bit clearer but there are still some questions.
    I connect to the internet via airport only and it is pretty fast.
    I was assuming airport in this statement in your first post meant the TC or the Express.. but I now realise we are still in the mass confusion stage where apple calls everything wireless an airport. So what you mean is the airport internal card of the computer??
    Also, I didn't want to bridge TC with my new fios router that I paid 100 dollars for, to get N speed and also paying 10 dollars more a month for fast speed.  I heard that bridging slows down everything and then there can be port issues with mail etc.
    I think this is mistaken.
    Putting the TC in bridge mode plugged into your FIOS will not slow the network.. nor will it cause mail or port issues.. in bridge the TC is just a fancy WAP and switch plus the network hard drive.
    If the computer is close it will be faster than the FIOS.
    You can run both wireless networks with different names.. so it is clear which is which. But you can also setup roaming so the computers themselves pick which is the best wireless.
    I tried extending the wireless net work and tried joining wireless network, but the TC kept crashing and I had to keep resetting the TC.  the Apple support person said these, extend wireless network and joint wireless network, are no longer a connection option with the new TC because of the new AC protocol.
    Thanks again!
    You cannot extend to a non-apple wireless router.
    You cannot use join a wireless network because when you do the ethernet ports will be cut off.
    But that has not changed.. I don't think Apple support is correct.. there has been no change with the AC model.. it is simply a fact that apple routers do not work in join wireless mode other than as a dumb client. The same applies to AC as to the earlier version.. but I have asked another person to check this.
    Join in the express is the only apple router that still allows an ethernet connection.
    For now you best use of the TC is bridged to the FIOS. Wireless you can sort out between several options.

  • Can you dual-boot arch linux with Windows 7 ?

    Here is my current dilemna; I have Windows still on my netbook for the only reason that I use it for gaming .
    Other than that I have Linux Mint dual-booted with it .
    Now my question is, can I just instruct arch to install into the already existing linux partition, formatting it and making it it's home, or do I have to delete it, thus rendering my computer inoperable until I successfully dualboot arch with it ? o_O
    Or should I take a different approach altogether, and triple boot my netbook with arch, mint, and windows, and then from there delete the mint partition and allocate the free space accordingly using easeus partition master (another reason I still have windows) ?
    Please help . D:
    PS. I HATE Windows but only kept it because apparently not everyone shares the Linux view of technology . >.>

    if youre happy with your partition layout u can just install arch ofc.
    while installing you will be prompted to select mount points and create filesystems ( you can skip the partition step )
    select your current / partition for, well, /
    and /home for.. /home.
    the installer will then create new filesystems there (formatting those partitions) and set mountpoints

    Hello; I am using Numbers '09 version 2.1 (436). I tried unsuccessfully to upgrade at one point. Now can't open existing documents. Message "The index.xml file is missing". How can I correct this ?
    Thank you
    Tom

    I't not iWeb that got damaged but the domain file. The index.xml file is inside the domain.sites file that's located in your Users/Home/Library/Application Support/iWeb folder. Do you have a backup of that file you can revert to?  If so then do it.  Otherwise a long shot but try the following:
    close iWeb.
    delete the iWeb preference file, com.apple.iWeb.plist, that resides in your Home/Library/Preferences folder.
    go to your Home/Library/Caches/com.apple.iWeb folder and delete its contents.
    launch iWeb and try again.
    If that doesn't help continue with:
    move the domain file from your Home/Library/Application Support/iWeb folder to the Desktop.
    launch iWeb, create a new test site, save the new domain file and close iWeb.
    go to the your Home/Library/Application Support/iWeb folder and delete the new domain file.
    move your original domain file from the Desktop to the iWeb folder.
    launch iWeb and try again.

  • At what percent e-tester can identify java applet objects. Plz see message.

    Hi,
    Me new to this group.
    I am here to find out whether e-tester can test java applet or not.
    I am testing a web application which is completely Java applet base.
    Envirnment used jdk1.1.8 and Jre1.4.
    I have been trying to identify applet object used in our application.
    problem i faced:
    when i set java option in option seting for both Microsoft applet and sun system applet. where my system having jdk1.1.8 and jre1.4.
    Recording on above envirnment I am able to record my application but i can not play that. On this case I marked Abbot script generated.
    when uninstall jdk and jre.
    I am able to record and play my application still some step. But I am not able to customize it.
    this application also uses StarTree a hyporbolic tree API from
    "Business Object" now bought by SAP (this api used inside applet
    frame).
    Is any one work on e-tester to automate in and out of an application which is built in java applet.
    Can some one help me to figure out where I am doing wrong.
    Before this I worked on e-tester year back to automate one of our application and still we are doing our regression on that.
    Expecting some help

    When you say customize, are you referring to parameters? They is handled differently with applets. I believe there is documentation on this.

  • How to test whether a table exists in database?

    How can I test whether a table exists in a database before I execute a query? If the table doesn't exist, I want first create a default table with certain name so that I can always display something in JTable.
    Thanks!

    Hi,
    There are tow ways :
    The first one is :
    - load the list of tables of the Database in a Vector for exemple by using methode DatabaseMetaData.getTables () and you can test if the table exist or not in the vector by using methode Vector.contains(Object o).
    The code seems Like that :
    // Loading List Of Tables
    // you need to load the list of tables at the begening of
    // your class
    Vector listOfTables = new Vector();
    try
    rs = yourConnection.getMetaData().getTables();
    while (rs.next())
    listOfTables.addElement(rs.getString(3));
    catch(SQLException exp)
    // When you need to test the existance of table name
    // you add this line
    if(listOfTables.contains(tableName))
    // your code
    The second one :
    try
    //execute your query
    catch
    //Create your default JTable
    I hope that my response can help you!

    Hi,
    When you say you get an error message running the MacOS x installer disc, is it when you boot on the CD or when you insert the disc in your SuperDrive during an open session? Have you tried booting from the CD and running the Apple Hardware Test? From your list of trouble, it looks like a bad RAM, or maybe a corrup hard drive sector, but it could be something else entirely. Next time you boot, try verbose (press Command-V right after the gong), you'll see every step of boot on screen, it'll give some indication as to what makes your MBP hang up. You can also try to run AppleJack in Single-User mode (first install AppleJack ; download from here :  http://applejack.sourceforge.net/ ; install as admin is required ; boot in SU by pressing Command-S at the gong): it's done wonders on my machine more than once...
    "Oh, one more thing"... Is there anything connected to your MBP via USB/Firewire/Bluetooth? If so, try and unplug/disconnect everything, then boot up, just so we can rule a bad driver out.

  • The application "Dropbox - test" can't be opened -1712

    I created two additional dropbox applications though Automator and they have been working fine with no problem along with my own normal Dropbox application. I have them all set to open on start up along with Google Drive so that they appear in the top bar on my Macbook Pro. They are also in the sidebar on Finder.
    The problem i am having is that when i start up my Mac, my normal original Dropbox opens and syncs however the other two don't open. When i go to Applications and click on either of the two to open then i am getting the message - The application "Dropbox - test" can't be opened -1712.
    I have been reading about this online and went to the Activity Monitor and forced quit these and they show up in red when i search for them. But then i still have no luck in opening them. I have allowed Applications to be opened from Everywhere in the System Preferences - Security section too.
    Its very strange how i have had this working with no problems and then it suddenly stops.
    Any help or suggestions anyone can give would be really appreciated.
    Thanks!

    Where are you choosing to download the install files too?  What is the status of the download in the Adobe Support Advisor?

  • Have been using successfully Acrobat 8 Standard, version 8.3.1 for years.  Suddenly can not digitally sign anything because software can not find "existing digital ID file?

    Have been using successfully Acrobat 8 Standard, version 8.3.1 for years.  Suddenly can not digitally sign anything because software can not find "existing digital ID file?

    Are you still using Acrobat 8? If not read further.
    All Acrobat versions prior to 11.0.07 had a security flaw that they allows signing with certificates that had "Extended Key Usage" (EKU) restricted to certain certificate uses and those did not include document signing. Most frequently those were certificates with "Client Auth" or "Server Auth" in EKU. Acrobat/Reader 11.0.07 fixed this problem, which also means that while previous versions accepted such certificates for signing 11.0.07 and later do not.

    1
    Close all iWork applications
    2
    Uninstall Keynote; this must be done with an application remover tool to delete the installation properly. Appcleaner is known to work correctly for this purpose, it is free and can be downloaded from here: Appcleaner Download
    3
    empty the trash
    4
    shutdown the Mac and restart. After the start up chime, hold down the shift key until the apple logo appears
    let the Mac complete the start up procedure completely, it will take longer than usual as the hard drive is being repaired
    5
    Reinstall Keynote by logging into the Mac App Store using download / install
