When fiddling with CentOS 6.x in a chroot:
- If your host architecture is x86_64 but your chroot architecture is i686 then you’ll find that yum update will try to install lots of x86_64 packages, and then fail. That’s because the arch command still returns “x86_64″. You’ll want to use setarch:
# arch x86_64 # setarch i386 /bin/bash # arch i686 #
- You’ll need to make sure you have a useful /proc as otherwise yum won’t be able to work out how much free disk space there is and will refuse to proceed. Bind mounting is probably easiest:
$ sudo mount --bind /proc /srv/your/chroot/proc
- You might find that things you install aren’t labelled correctly for SELinux. If this is a virtual machine then you can force it to relabel on boot:
$ sudo touch /srv/your/chroot/.autorelabel
fixfiles may also work, but I haven’t tried that.
Thanks to Alex for the setarch tip which I had not come across before.
