Under what conditions would you need to boot the 32-bit chroot natively? I have never needed to, so my chroot is uner /srv/chroot/etch-ia32. I put /srv on its own LV (I use LVM over raid1). I used debootstrap to install the chroot following (loosly) the instructions in the amd64 howto from the debian website. I access the chroot with $ schroot -pc etch-ia32 which means that I have the schroot package installed on the amd64 system. Once debootstrap gives you a basic system, you schroot into it, run aptitude, and setup what you want. Treat it like its own machine.

chroot question
I have observed some odd behaviour since setting up a 32-bit chroot (in order to run some weirdy Java web applet.) This chroot is totally self-contained, even with its own /home directory (so that my 32-bit application preferences don't clobber my 64-bit ones). If I already have 64-bit Iceweasel running, and try to start 32-bit Iceweasel from inside the chroot, I get another instance of the 64-bit browser. If I kill the 64-bit browser, I can start a 32-bit one. If I then try to start a 64-bit Iceweasel from the K menu while the 32-bit Iceweasel is running, I get another 32-bit Iceweasel. The upshot seems to be, I can't have both a 32-bit and a 64-bit Iceweasel browser open at the same time. I'm guessing this is due to some kind of namespace conflicts. Would it work if I modify the source package slightly, to change the name of the application and call it something like iceweasel32 instead? -- AJS delta echo bravo six four at earthshod dot co dot uk -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Hi, I never try to run simultaneously 32 and 64 bits version of Iceweasel. I want to be able to use the two versions of firefox so i not uninstalled no version, i simply install schroot and a script /usr/bin/firefox32 which contains following lines : #!/bin/bash schroot -p firefox $1 exit Here is also my config for /etc/schroot/schroot.conf [etch] description=Debian etch (stable) 32-bit location=/var/chroot/etch-i386 priority=3 users=toph #groups=toph,root root-users=root #root-groups=root #groups=sbuild-security aliases=default,stable,ia32 run-setup-scripts=true run-exec-scripts=true type=directory personality=linux32 This method affords me to use one and one only one home for the 32 and 64bits application.

I run both a 64-bit and a 32-bit Iceweasel simultaneously with different profiles and the -P option, but my /home is shared in the chroot. -- Eu não sou tão idiota como você parece.

While this should work it is not necessary for many 32-bit applications. They will run fine if called directly outside the chroot. The 32-bit libraries need to be listed in /etc/ld.so.conf and /lib/ld-linux.so.2 (the 32-bit linker) needs to be present (possibly as symlink to /chroot32/lib/ld-linux.so.2). Then, many applications will run fine in the 64-bit environment and they can easily call 64-bit applications. Matthias -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Then, since it is a chroot, you can only see what's inside /ia32. /usr and other directories are not accessible from the chroot. Unless you someway make /usr visible inside /ia32, perhaps with a bind mount. You would also need other directories (such as /var) if the application needs them, and configure the application to use those directories. The same happens to libraries. If /usr is bound to /ia32/usr64, you'll need to tell the library loader to look for libraries there. Messy, really messy. What you can do is install the 32-bit version of the program inside the chroot, and it'l run fine. -- Sometimes I live in the country, And sometimes I live in town.

Re: chroot question
You can also use something like ssh localhost to escape the chroot, although it adds a bit of overhead. - M On 1/21/07, Eduardo M KALINOWSKI [EMAIL PROTECTED] wrote: Anton Piatek wrote: I posted this on Debian-user list, but thought someone here might have tried this already...
