Setting up a slim 32-bit chroot
My purpose of setting up a 32-bit chroot is to play some 32-bit games. When I install nvidia, it pulls in a bunch of other dependencies, such as kernel26, mkinitcpio, xorg (via nvidia-utils), and probably a bunch of other stuff.
The wiki wasn't exactly clear. At first it said I could clean up the environment a bit by getting rid of kernel26 and mkinitcpio. However, it says to install nvidia, simply put:
# pacman -S nvidia
Like I said, this pulls in a BUNCH of things, which may or may not be necessary. The kernel I'm not so sure about, but I'm pretty sure I don't need mkinitcpio and another X server running.
If hard disk space is not a big problem, I'd suggest just leaving things as they are. If it is, you should just force remove them after installing nvidia. Be aware that the next nvidia update would probably pull them back in, and you'd have to do it all over again.
You could probably just have a script to remove everything you know you won't need (don't forget to clear the cache).

[SOLVED] Problems with setting up 32-bit chroot environment
Recently I've moved to Arch64 and decided to build chroot environment in order to have a working flashplugin, Java and some other applications without messing up system libraries of two different architectures. I've followed directly instrucions from the wiki, but unfortunately still can't make it work. I'm stuck with
Kod:
bash-3.2# /etc/rc.d/arch32 start
:: Starting Arch32 chroot [DONE]
bash-3.2# xhost +local:
No protocol specified
xhost: unable to open display ":0.0"
bash-3.2# chroot /opt/arch32
I've googled a lot, asked on Polish Arch Linux forum, but so far I wasn't able to find a working solution. Can someone more experienced give me a hand with this?

I have the arch32 daemon in my /etc/rc.conf and I run this when I want to use the chroot:
#!/bin/sh
/etc/rc.d/arch32 start
xhost +local:
chroot /opt/arch32 su -l username -c "linux32 zsh"
Is it similar to your setup? -
Not enough disk space in 32-bit chroot [SOLVED]
Hi all,
I am trying to set up a 32-bit chroot on my Arch64 system.
I have followed the steps detailed in the wiki http://wiki.archlinux.org/index.php/Arc … bit_system
When I tried to install the fonts, it complained of not enough space on the disk:

This is strange, as my disk space is as follows:
df -h #(from my 64-bit system)
Filesystem Size Used Avail Use% Mounted on
/dev/sdb3 69G 2.7G 63G 5% /
none 1007M 0 1007M 0% /dev/shm
/dev/sdb6 66G 23G 43G 35% /home
/dev/sda1 150G 32G 118G 22% /mnt/windows
But from the chroot:
df -h
df: cannot read table of mounted file systems
Is there anything I'm doing wrong here?
Thanks

Architecture = auto
Multilib is not mentioned in /opt/arch32/etc/pacman.conf. I assume that means that it is disabled? -
Arch32-light: minimal 32-bit chroot
Project page: http://xyne.archlinux.ca/projects/arch32-light
*edit: check the project page above for up-to-date information*
I finally got around to going through the 32-bit chroot setup guide in the wiki and ended up with this. The project and man pages should explain everything.
As always, questions, suggestions and feedback are welcome.

If you look closely at the arch32.conf file, it doesn't actually copy over files that don't yet exist in the chroot. Both locale.gen and locale.sh will only be copied if the user has installed locale-gen in the chroot. I've done it this way to avoid file conflicts when installing packages in the chroot with pacman.
Ah, I missed that. Thanks for the clarification.
The bauerbill alias that you've posted needs to be changed to work with arch32-light because the pacman32 configuration file and mirrorlist are located at /opt/arch32/etc/pacman32.conf and /opt/arch32/etc/pacman32.d/mirrorlist. This is to ensure that pacman32 in the host remains independent of pacman in the chroot (the base installation doesn't even include pacman in the chroot).
Yes, I caught that right after I posted it. I'll fix the alias.
Edit: Done.
I've never actually used schroot so I didn't know that it mounted anything itself. Note though that all the hook does is make sure that the daemon is running, which is expected anyway, so I don't think it can hurt to have the extra check. Aside from ensuring that the correct directories are mounted in the chroot, it also prevents files from being created inside the empty mountpoints.
Schroot has a precofigured makeshift fstab file for arch32 under /etc/schroot/mount-arch32. Since I never really did anything else with my chroot aside from running applications installed by pacman32 (or bb32 in my case), I left it to schroot to mount my stuff. That way I also didn't need to run the arch32 daemon the wiki specified. If I actually needed shell access to the chroot, I just launched schroot -p -- bash or schroot -p -- zsh. (I don't know if this could give rise to any security issues, though). I didn't try the more exotic cases however, like installing applications that need to change CDs in the middle of the process in chrooted wine…
I'll play around with schroot a bit to see if any issues come up with the mounts.

[SOLVED]How to use pulseaudio with in 32 bit chroot on ARch64
I am trying to running some 32bit software from chroot environment on Arch64.
I set up pulseaudio on Arch64 property.
However, within 32 bit chroot, I cannot use pulseaudio.
For an example,
arch32 chroot /home/xxxx/Audio > paplay Front_Center.wav
Connection failure: Connection refused
How can I fix this?
Last edited by phabulosa (2008-04-27 19:37:15)I made this to work by the following steps:
1. Install pulseaudio and alsa-plugin stuff in Arch32;
2. Edit /etc/pulse/default.pa on Arch64 and enable "load-module module-native-protocol-tcp";
3. Edit /etc/rc.d/pulseaudio and add a line "cp /var/run/pulse/.pulse-cookie /opt/arch32/etc/pulse-cookie" after pulseaudio line in 'start' part;
4. Add some lines in /etc/hosts.allow on Arch64 (some of them may not be necessary) ;
pulseaudio-native: 127.0.0.1
pulseaudio-simple: 127.0.0.1
pulseaudio-cli: 127.0.0.1
pulseaudio-http: 127.0.0.1
esound: 127.0.0.1
5. Follow the "PulseAudio over Network" in Arch Wiki on Pulse audio http://wiki.archlinux.org/index.php/Pul … er_network and configure my Arch32 as a remote client on the network while setting the server address as 127.0.0.1;
6. Restart Pulseaudio daemon on Arch64 and Run "paplay" on Arch32 to test. -
I set up a 32 bit chroot for zsnes, as per the directions given in the wiki. Standardly, everything works fine, and running
dchroot -d zsnes
loads it just fine.
I didn't want the chroot to have access to my home directory, though, so I commented out the lines in /etc/rc.d/arch32 that mount-binded /home to /opt/arch32/home. I copied my ~./zsnes folder to /opt/arch32/home/my-username/.zsnes, figuring that zsnes wouldn't be able to tell the difference between that and the default setup. However, without /home mounted, when I try to run zsnes, i get:

[solved] Wine with 3D under 32 Bit chroot - any how2 ?
Hi fellow archers,
I have set up a 32 Bit change root as discribed in the wiki here:
http://wiki.archlinux.org/index.php/Ins … _in_Arch64
The installation and configuration worked pretty straight forward. Unfortunately WINE doesn't find 3D acceleration. I installed Mesa inside the chroot but it lists softwaremode for the renderer when I do a glxinfo.
Do I need to follow the ATI guide in the wiki and install some libs like this ?
pacman -S libgl ati-dri
Or do I need to completely build Mesa within the 32 bit chroot ?
TIA,
D$

BTW: A CDROM mounted inside the chroot seems to be accessed different from being mounted inside the native linux environment.
At least Starcraft tells me that the original CD is not inserted although it is my original CD is inserted in the DVD drive. Under 64 Bit Ubuntu 9.04 works fine with WINE and the original CD.
Do I have to change my mounting approach ?
First of all: Do you use schroot and have your --bind mounts set up properly?
The Arch Linux Wiki wrote:mount --bind /proc /opt/arch32/proc
mount --bind /proc/bus/usb /opt/arch32/proc/bus/usb
mount --bind /dev /opt/arch32/dev
mount --bind /dev/pts /opt/arch32/dev/pts
mount --bind /dev/shm /opt/arch32/dev/shm
mount --bind /sys /opt/arch32/sys
mount --bind /tmp /opt/arch32/tmp
mount --bind /home /opt/arch32/home
You can just add the path to your arch32 rc.d script (if you use that) or to mount-arch32 (if you use schroot), e.g.
mount --bind /media/cd /opt/arch32/media/cd
Anyways, CD checks are a weird matter with wine… I can't get Warcraft III to recognize the CD either, so I'd just cross my fingers -
Automate gaming in 32 bit chroot ?
Hi fellow archers,
Gaming with WINE inside a 32 bit chroot works perfectly for me. I just want to add some more comfort.
I have not really found a good description on how to automate gaming within a 32 bit chroot.
There is a hint in the wiki to add an alias which launches wine inside the 32 bit chroot from your 64 bit system but how would I write a script which does:
1) Mount an ISO required for a windows game as loopback
2) Start the 32 bit chroot
3) Start the game via WINE inside the 32 bit chroot
4) Exit the 32 bit chroot
I know how to do this all inside a terminal manually but
...how do I "change into 32 bit chroot" from a bash script ?
...how do I call WINE inside the 32 bit chroot from the same bash script ?
...how do I exit the 32 bit chroot from the bash script ?
Additional to this I am not shure if it is smarter to mount the ISO inside the 64 bit system and export the directory to your 32 bit chroot ? Or is it smarter to change inside the 32 bit chroot and mount the ISO there ?
I am asking this esp. in regard to some "CD checks" of Windows games which sometimes seem to be very sensitive in regard how the media is mounted / presented to WINE itself.
As usual I would like to write things together and add them to the corresponding part of the wiki.
TIA,
D$Hi Runiq,
Thanks for your help again !
Using schroot works perfectly for me when I use it to run darkplaces together with SDQuake.
In order to do more than one command within the chroot I guess I simply have to write shell script and launch this inside the chroot via schroot, right ?
I am not shure how schroot takes care for mounting / unmounting when I have several ISOs lying in my home directory which I require for different games. A lot of games work fine with "no-cd" patches in term of requireing the original CD but still rely on files stored on the CD.
My best guess is a combination of two shell scripts. One running under arch64 and one which is started via schroot in my chroot.
Cheers,

Autostarting a daemon from a 32 bit chroot
hello
i have arch64 and a brother dcp 135c printer. brother does supply drivers for linux but unfortunatelly for 32 bits only. because i have a 32 bit chroot, i thought i would just remove cups, and then inside the chroot install cups again, install the driver and add the printer. i did it and it all works fine except for one thing: i don't know how to autostart the cups deamon (inside the chroot) on boot.
i tried adding cups32 to my list of deamons in rc.conf. first what i put in it was
schroot -p /etc/rc.d/cups $1
but it didn't work, so i tried
chroot /opt/arch32
/etc/rc.d/cups $1
exit
but with no more luck.
here's what i get when i try to start cups not from inside chroot:
# schroot -p /etc/rc.d/cups start
I: [Arch32-801204e2-dcae-4c65-901f-145b605d70e9 chroot] Running command: "/etc/rc.d/cups start"
:: Starting CUPS Daemon [DONE]
ps aux | grep cups
root 6027 0.0 0.1 8752 996 pts/0 S+ 14:13 0:00 grep cups
as opposed to
root 6036 0.0 0.5 8720 2628 ? Ss 14:15 0:00 /usr/sbin/cupsd
when started from inside chroot.
could anyone help me please?I am having the same issue. I want to start distccd, but when I run schroot /etc/rc.d/distccd start, it says [DONE] as usual, but the daemon doesn't come up in ps -A. if I manually chroot into /opt/arch32, I can issue the same command and it'll stay running. I'm assuming that schroot sandboxes the environment, and when the command releases the terminal, it kills all the processes associated to it.
How can I keep daemons running when they are started by schroot? -
Pacman 3 in 32-bit chroot = no go
Trying to use pacman 3 under my 32-bit chroot doesn't work at all, the problem is pretty obvious since it complains about no free space. Which isn't so weird after all, mount shows _no_ mount points at all, no wonder pacman can't decide if there is any free space or not, / isn't even mounted!
I actually created the 32-bit installation by simply installing Arch onto another partition and just not install any bootloader so it should be fully working if I add an entry into my grub menu.lst. I then borrowed the rc.d script from the wiki (http://wiki.archlinux.org/index.php/Arc … _rc_script) and everything has been working fine until I upgraded pacman.
Anyone have any idea on how to make it work with pacman 3?You did bind-mount proc, dev and sys into the chroot?
If you did, maybe a
# grep -v rootfs /proc/mounts > ${CHROOT}/etc/mtab
(from outside the chroot) helps

Xorg-server 1.9 excessive CPU usage through a 32-bit chroot - bug?
Xorg goes crazy tapping my cpu usage when I compile in a 32-bit chroot. >60 % of the total CPU is going to Xorg rather than to gcc (running Gnome if that matters). The htop screenshot below shows X and gdm using it. I know that if I start gnome from init 3 without gdm the same problem occurs except htop just shows X as the culprit.
X :0
Further, packages fail to build when I run makepkg through X. If I run it when I'm in init 3 without X at all the very same package successfully builds. If I leave myself logged into Gnome and open tty1 and enter the chroot there, it builds.
Any thoughts why? That has to be a bug in Xorg given the conditions I explained above. Does anyone have an idea as to preventing this?
I entered the 32-bit chroot via: linux32 chroot /opt/arch32 /bin/bash
The package I was attempting to build under X is a kernel if that matters; here is the last bit of the log before the error:

Users cannot access removable devices after you enable and then disable a Group Policy setting on Windows 7 64 bit machines.
on the 32 bit machines I was able to apply this hotfix

But it will not install on 64 bit machines.
Is there a hotfix for 64 bit? If not, what is the work around?
