I have a 32-bit PXE environment and I want to chroot
to a CentOS x64 root filesystem. Of course that doesn't work. Any tricks or hacks that would allow me to do that? Currently I get the error:
chroot: /bin/bash: Exec format error
What if I updated my PXE environment to 64-bit.
Could I then chroot to a 32-bit?
I use PXE to quickly troubleshoot both 32-bit and
64-bit arch.
Thanks. -Scott
Booting an x86-64 kernel with the proper config options set to enable execution of 32 bit binaries should allow you to do that. I think.

Yes - chroot from x86_64 to i386 works fine.
Here's a fairly complete method to setup enough of a chroot to use yum and rpm. The host is x86_64 and the chroot will be i386 in LVM.
