I'm using Fedora core 2 with kernel 2.6.8-1.521. I did a very stupid thing and forced uninstalled glibc-2.3.3-27.i386.rpm. Linux became unuseable and won't reboot now (kernel panic).
I booted from CD 1 with 'linux rescue' figuring that as a reinstall of glibc-2.3.3-27.i386.rpm would correct my problem.
While in rescue mode if I do 'chroot /mnt/sysimage' (as instructed) I get the message 'cannot execute /bin/sh: no such file or image'. However /bin/sh is present and works fine from both / and /mnt/sysimage.
