Hi!

Something wrong with unionfs, look at this:

[dsh@neva dsh]$ mkdir /mnt/.ro
[dsh@neva dsh]$ cp -R /bin /lib /libexec /mnt/
[dsh@neva dsh]$ mount_unionfs -r /usr /mnt/.ro
[dsh@neva dsh]$ jail /mnt x.x 127.0.0.1 /bin/tcsh
# pwd
/
# cd /.ro
# pwd
/.ro
# cd /.ro/bin
# pwd
pwd: .: No such file or directory

Why pwd said this? What is wrong?
