#26 Mounting twice or more

[Anonymous]

It is possible to mount the same directory a lot of
times. I think it could be dangerous, although it
hasn't happened anything bad to me. See an example:

debian:~# uname -a
Linux debian 2.4.17 i686 unknown
debian:~# cat /etc/fstab | grep ftp
none /hb ftpfs ip=XXX,user=XXX,pass=XXX,uid=1000,
gid=1000,root=/users/SL 0 0
debian:~# mount /hb
debian:~# mount /hb
debian:~# mount | grep ftp
none on /hb type ftpfs (rw,ip=XXX,user=XXX,pass=XXX,
uid=1000,gid=1000,root=/users/SL)
none on /hb type ftpfs (rw,ip=XXX,user=XXX,pass=XXX,
uid=1000,gid=1000,root=/users/SL)
debian:~# umount /hb
debian:~# umount /hb
debian:~# umount /hb
umount: /hb: not mounted

Is it dangerous or not, this behavior is inconsistent
with the other filesystems.
