[CentOS] chroot from 32-bit to 64-bit filesystem?
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 ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I'm pretty sure that you can run 64 bit executables only when you're running a 64 bit kernel. If you install and run a 64 bit kernel in your system without changing anything else, you should be able to chroot to a 64 bit environment. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Glenn 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. http://paste.ubuntu.com/517149/ -- Mark ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
