chroot cannot change kernels. It is, however, safe to chroot into the root filesystem of a system which normally runs a different kernel version. > - I heard all the fuzz about un/mounting the /proc, but I can't find any > documents on that.

If you don't have it mounted, things like 'ps' will fail. You can mount it by running in the chroot: mount -t proc proc /proc And to unmount just: umount /proc If you don't unmount /proc, you won't be able to unmount the filesystem it's mounted under. > - I need to apt-get from the chrooted system. but on my 1st attempt, I > was not able to connect to outside, even ping.

Try copying /etc/resolv.conf from your host system to the chroot's etc/resolv.conf.
