Don't give up hope Roman. :)
If it's of any use, I updated yesterday, and I get the following
behavior. As a regular user, or as root, and without chroot, I get:
/compat/linux/bin/ls
/compat/linux/bin/ls: error while loading shared libraries:
/usr/lib/librt.so.1: ELF file OS ABI invalid
As root, with chroot, I get:
chroot /compat/linux /bin/ls
bin etc lib media mnt opt proc sbin selinux srv sys usr var
hth,
Doug
