Mount Command

For this command: mount -F UFS -o rw,remount /usr

mount -F UFS -o ro,remount /usr -- doesn't work for me (read only mode).

Frankly speaking, I've only been able to remount for read/write (rw). I've always had to reboot the system for read only (ro) to take effect.

Thanks.

See the mount_ufs man page - remount option remounts a read-only file system as read-write. The option works ONLY on currently mounted read-only file systems.

I'll look it over...
