ncpumount - unmount a NetWare filesystem mounted with ncpmount.
This utility unmounts a NetWare filesystem that was previously mounted
with the ncpmount utility. If the this utility is made suid root then
non-root users will also be able to make use of it.
has been written to give normal linux-users more control over their
resources. It is safe to install this program suid root, because only
the user who has mounted a filesystem is allowed to unmount it again.
For root it is not necessary to use ncpumount. The normal umount
program works perfectly well, but it would certainly be problematic to
make umount setuid root.
