Using CentOS 4.1 (RHEL equivalent) as root with bash as my shell, I
reviewed the man pages and info for chroot, did ldd for /bin/bash, and
got the following:

# ldd /bin/bash
         libtermcap.so.2 => /lib/libtermcap.so.2 (0x00d77000)
         libdl.so.2 => /lib/libdl.so.2 (0x00c98000)
         libc.so.6 => /lib/tls/libc.so.6 (0x00b48000)
         /lib/ld-linux.so.2 (0x00b2f000)
[root@localhost /]#

So I then created the following directory setup:

# ls -Ral /crtest
/crtest:

[root@localhost /]#
[root@localhost /]#

Then, when I try chroot /crtest I get:

# chroot /crtest
chroot: cannot run command `/bin/bash': No such file or directory
[root@localhost /]#

Obviously, I am missing something here.

Any help appreciated.

Thanks

Apollo
