ArchLinux chosen a default distro for our faculty.

I'm happy to inform that we decided to make ArchLinux a default distro for our student workstations (approx. 200) and main servers (12) at the Faculty of Mathematics and Information Sciences, Warsaw University of Technology. Previously we've been using Gentoo for those purposes. For workstations the new choice was obvious. For the servers - it was not. Honestly, we are a little disappointed with ArchLinux migrated to systemd. Personally, we are not convinced in systemd advantages and worry about possible future incompatibilities with other systems/distros and security issues. However, we finally decided that other advantages of the ArchLinux distribution outbalance any doubts related to systemd. We believe it's a good choice.
Thanks to ArchLinux developers; keep your good work!

We are facing a similar big decision: Using Arch Linux as the distribution for a "thin client with good offline capabilities". The numbers are comparable (approx. 250 clients). The problem is that the clients are spread across the country and are not easily reachable by IT staff.
Our test setup and results (approx. 5 computers) so far:
We use a dual boot setup: One recovery partition with a bare minimum install (only base group + some tools) and a script to save and restore another partition. This other partition has a full installation with Xorg, LibreOffice, Firefox, rdesktop/RDP etc. Let's call this the "production system"
By default the production partition is booted by GRUB and the recovery partition can be manually selected from the GRUB menu
The recovery partition (when booted) is accessible by SSH (the production system also)
The "production" partition can be backed up with an rsync script and can be restored from the recovery partition if an upgrade of the production partition goes wrong and the production system does not boot anymore
Even the recovery partition can be backed up and updated from the production system (arch-chroot) if it can be guaranteed that the production system is booting the next time
The 5 computers are in a real-world test setup since a few weeks and well, it works ;-)
Some unresolved problems/questions remain:
How do we test possible updates for all clients? Maybe in a virtual test machine...
How do we update all or most of the clients at once? I'm thinking of a local/custom repository and using parallel ssh or something.
How do we deal with special setups (other packages, other configuration? Perhaps using someting like cfengine...
How should the user accounts be configured (we have LDAP)? Well, that's not an Arch specific problem ;-)
@quayasil perhaps we can share our thoughts/work and create a blog/wiki or something about such a setup if the results are usable?
Some thoughts?

  • How to change default thresholds for some metrics of all targets.

    Hi!
    We have a lot of servers which have to work hard.
    So, our OEM very often generates messages like these:
    "EM Alert: Critical:dbsora90.tsb.kz - CPU Utilization is 99.95%, crossed warning (80) or critical (95) threshold."
    "EM Alert: Critical:dbsora94.tsb.kz - Disk Device c8t60A9800043346C384C344A4A63516D6Ad0(ssd4) is 99.7% busy."
    "EM Alert: Critical:dbsora94.tsb.kz - CPU Load (Run Queue Length averaged over 5 minutes) is 20.78, crossed warning (10) or critical (20) threshold."
    I need to change default tresholds for mentioned metrics but I can't their defenition in SYSMAN.MGMT_*-tables or suitable settings in OEM GUI.
    And I have no time to edit treshholds manually for each target. )

    Modification of Metric Thresholds (as this is what you are referring to), should be done using the Metrics and Policy Settings link (to be found in the Target Home page).
    Don't mess around with the SYSMAN tables!
    Best thing to do here is to start using Monitoring Templates for this.

    I have just started to use Muse for our design agency and learning how to build ourselves a new site, I have managed to create a basic lightbox which contains sliding images, what I need to do now is have a pop up window which goes into detail about the projects, what I would like is a piece of text  or icon that when you roll over it and then click a separate window pops up with additional information in, once finished reading the info you can then click to close the box, any advice on how to do this?

    The best way to do what you're asking is with the Composition widget. Start with the Tooltip preset, which, by default shows the info on rollover. You can change the option to show on click, which is what you're after. You can also add the close button or have the info disappear on rollout.

  • How to create an default profile for every user on one machine? Deployment of configurations?

    On firefox 3.5.X i can copy an configured profile from an user-folder to the programm folder of firefox. \mozilla firefox\defaults\profiles.
    After an new user log in to the machine the default profile will get the actual profile of the new user. With all bookmarks, configurations and so on.
    But this doesn't work with the firefox 3.6.10? What changed? What will be the way i can get an default configuration for every user on one machine? I want to deploy the firefox with an default configuration in our enterprise? Why does the behaviour change?
    What to do?
    Thanks...

    No - there are no missing data, because nothing will be copied. The profile - folder does not work.
    There are the standard first start behavior.
    There might be another trick? Hint? Todo?
    Thanks.

  • Is it possible to create a new tab in 'Default settings for items' option?

    Hi everybody
    I am Raghu working in EBP2.0 & I have come across a difficlty and that is of creating a new tab and also the fields 'GL a/c', 'cost centre' or 'internal order' in this new tab.
    First of all please let me know whether is it possible to create a new tab for these fields.
    The purpose of this new tab is to default the cost centre and GL account with reference to shopping cart.
    As per current scenario, user has to enter the cost centre & the GL code as many times as the number of items in a shopping cart. I mean, if you have 10 items in your shopping cart then 10 times user has to input the cost centre & GL account. To avoid this we are required to add new tab so that per shopping cart we can enter the GL account & cost centre only once.
    Your immediate response would be very much apprecited.
    Regards
    Raghu

    hi Ram & Sreenivas
    Thanks for your immediate response.
    Ram, we can default GL a/c & cost centre in org structure since client wants to us to keep the option of entering these for every shopping cart.
    Sreenivas, I checked the 'copy to clipboard' option & its not there in EBP2 and I feel what you meant as cost centre tab is account assignment tab.
    Let me explain you more clearly about this requirement.
    Current Scenario
    1.Say a user has added 5 items to his SC.
    2.User has to enter cost centre & GL code 5 times & then he can order
    Required scenrio
    1.Say a user has added 5 items to his SC.
    2.As per the proposed functionality, user will click on 'Default settings for items' button. Three tabs will appear-->Basic data, Internal note & Delivery Address.
    We have to provide a new tab here where in user will default his GL & cost centre for this shopping cart & then order. This will help user to avoid entering GL & cost centre 5 times.
    For some reasons our client is not interested in defaulting this data.
    Please help in this regard if time permits.
    Thanks

  • Default Value for Order Type based on Company Code  in ME21N

    Hi,
         Using ME21N, I want to make the PO type defaulted to a certain company code, say for instance Company code  XYZ should have a PO type XYZ Purchase Order, ..company ABC should have a PO type ABC Purchase Order, and so on...I'm just puzzled how to implement it. I know that we can set a Default value for PO Headers in Personal Settings but its doesnt give the result I want coz it will only have one Default Value. What I wanted is when a certain company code is chosen, automatically, the corresponding PO type for that Company code will be displayed in the Order Type drop-down menu (so there's no need to choose on the drop down list what Order type) Is this possible in ABAP? Hope i made myself clear.
        Thanks in Advance.

    Use BADI IF IF_EX_ME_PROCESS_PO_CUST - method OPEN
    View the interface documentation in transaction SE19 and you will see the method OPEN can be used :
    2. Opening of a purchase order (OPEN method)
    The system opens a new document to create, change or display a purchase order. With the OPEN method,
    <b>you can import your own data and prepare it for further processing.</b>
    This is available in 4.7 Enterprise but not sure how far back.....
    hope this helps

  • How to set default preferences for an enterprise rollout installation?

    How do I establish my own default skin, color scheme and canvas size for an enterprise-wide rollout of X2008 SP3? 
    I have found the Xcelsius.ini file in the root install directory (C:\Program Files\Business Objects\Xcelsius). 
    If I change the skin value in this file to Nova, Xcelsius correctly sets the skin to Nova when running the app.  But it completely ignores my changes to width, height, and colorScheme.
    Is there some other location where these preferences are stored?
    Also, where are my custom color schemes stored?  I would like to include those in my enterprise-wide rollout as well.
    Thanks!
    Chris

    I found my own answer to this question.  The only xcelsius.ini file that seems to matter is the one in the user's Application Data folder under C:\Documents and Settings.  Also, any custom color schemes are stored there as well.
    So for our enterprise-wide rollout, we will just place our versions of those files in that location.

  • Shopping Cart - Default Settings for items

    Hi all,
    We are on SRM 7.0  SP05 classic scenario with backend ECC 6.0 EHP4.  There is a requirement to retain shopping cart default settings so that user is no need to enter default values on each shopping cart creation.
    We are intent to develop a custom WDA for users to edit their own shopping cart default settings, the values will be saved to user position attributes and extended attributes (including some customized attributes) at PPOMA_BBP.  After that, default settings will be copied from attribute during shopping cart creation, for example:
    Item Basic Data: Product Category <== extended attribute "Product Category" value which is set as default
    Account Assignment: Account Assignment Category <== attribute KNT which is set as default
    Assign Number: Cost Center <== attribute CNT,  Asset <== attribute AN1, WBS Element <== attribute PRO  (plus two custom attributes to hold value of Internal Order and Network)
    Here are the questions:
    (1)  For GL account, we did not config combination of Product Category and Account Assignment Category in SPRO, we will create a custom attribute as mentioned above.  However, where can we insert our coding to copy custom attribute value to default setting during shopping cart creation?   Is class /SAPSRM/CL_PDO_USER_CONTEXT  a candidate?  If yes, which method should be enhanced?
    (2)  For Delivery Address, if we do not use standard address management and maintain value at attribute ADDR_SHIPT, we intent to use similar approach: maintain custom attribute and then populate to default settings.  The same question is where can we insert our coding to copy custom attribute values to default setting during shopping cart creation?
    Thanks.
    Regards,
    Donald

  • Can you set default values for person/group picker fields? To current user?

    Two-part question/issue . . .
    Part 1:
    In InfoPath 2013 in use with SharePoint 2013, how do you set a Default Value for Person/Group Picker fields? Other field types like Text Boxes have a Default Value section in the Data tab of Properties.  There doesn't appear to be any equivalent for
    the Person/Group Picker field type in Properties.  I'd like to set a default person for a few fields in a form I've created.  Is this possible?
    Part 2:
    The default user I want to set for one of those Person/Group fields is the "current user."  I want a user to log into our SharePoint 2013 intranet, load a new form for edit/creation, and have one of the Person/Group fields in that form to
    automatically populate this particular user.  Is this possible?

    Hi Stephen,
    You can auto populate your InfoPath farm with current user Name and all other property that you have in your User profile, you have couple of options.
    First you can make a secondary connection in your InfoPath form with user profile and can use the UserProfileService.asmx and call the GetUserProfileByName method. Here is the steps you can follow.
    http://blogs.technet.com/b/anneste/archive/2011/11/02/how-to-create-an-infopath-form-to-auto-populate-data-in-sharepoint-2010.aspx
    Secondly you can use JQuery and SPServices ,
    $().SPServices.SPGetCurrentUser function to populate the values with script to achieve the same in this case you no need to use InfoPath form just create simple text type column in SharePoint
    list and auto populate it with getting the current user Name from User Profile here is the scripts
    <script language="javascript" type="text/javascript" src="../../jQuery%20Libraries/jquery-1.4.2.min.js"></script>
    <script language="javascript" type="text/javascript" src="../../jQuery%20Libraries/jquery.SPServices-0.5.4.min.js"></script>
    <script language="javascript" type="text/javascript">
    $(document).ready(function() {
      var userCurrentName = $().SPServices.SPGetCurrentUser({
        fieldName: "CurrentUser"
      $("input[Title='CurrentUser']").val(userCurrentName);
      var userPhone = $().SPServices.SPGetCurrentUser({
        fieldName: "WorkPhone"
      $("input[Title='Phone']").val(userPhone);

    Dear Laurent,
    Yeah, this is a very strange issue and also a rare one. We have already tried this option. User deleted the cart and created a new cart. But still no luck. The new cart is also not getting released from SOCO. User created many carts previously for different product categories, vendors and all carts were through. But for this cart,it is not getting released. If you could have any other idea, you are most welcome.
    Anyway, thanks so much for your time and patience. Appreciate your help!!

  • Default entry for Folder property - Changed behavior in SP14???

    Hello,
    Has anyone run into changed behavior for this page property in SP14. It seems to be valid for pages in both folders and worksets.
    Ex. We have a workset that sits at 2nd level nav just below a 1st level entry point. So the workset is a 2nd level nav choice. The top page in that workset is the landing page for that nav and previously in SP9 the nav worked fine. We are finding now that in SP14 we have to set the Default Entry for Folder property to "yes" to make the 2nd level nav work. This could be another config issue in our environments but is following SP14 so far. Has anyone else sen this?
    Thanks,

    Hi Daniel,
    NavStructure:
    ... -  Folder A
           - Page A <inv & defPage>
           - Page P1
           - Page P2
    If you click on folder A, you get the content of page A which for the end-user is not explicitely visible in navigation. So page A "is" the content of folder A.
    This is how web-like nav works, that you can click on a nav entry and that this entry has it's own content and not only the preset content of some sub entry.
    Hope it helps to understand what I meant

  • ITunes doesn't recognise iPod as the default player for audio files.

    A few weeks ago my husband completely re-installed our laptop, without properly looking at how to backup my iPod touch. Everything was lost and I have had to start again, however the system still comes up with this message each time I plug the iPod in:
    iTunes has detected this is not the default player for audio files. Would you like to go to the Default Program Control Panel to fix this.
    I go to the Control Panel, but have no idea what to do.
    Can anyone please help me?
    I have not upgraded to version (4.0)
    Thanks in advance.

    Hello Geordie81,
    And welcome to Apple Discussions!
    Are you sure it wasn't referring to making iTunes the default application for audio files as described in this Apple support document? Worth a shot anyways.
