Can't delete a directory that WAS a mount point
Hi
I'm sure this is something stupid, but I can't figure out what I'm doing wrong. This is occuring on a Solaris 8 SPARC system:
sunnw: ls -l /mnt

Thanks for the suggestions, but they don't work.
Thanks!

Well, that's wierd: a 'umount /mnt/dakota11-1a' succeeded. And, following this, a 'rm /mnt/dakota11-1a' succeeded as well.
So, even though 'mount' showed that the mount point wasn't in use, and no entry for this mount point existed in /etc/vfstab, there was still a phantom mount in the system.
I'm all set now; thanks for the help!
