Jails on ZFS

[Artis Caune]

Hi,

I'm playing with jails on ZFS and everything is fine, except annoying
warnings (hopefully just warnings) when doing:
    # /etc/rc.d/jail stop

zfs_umount:971[0]: Force unmount is experimental - report any problems.
...
zfs_umount:971[0]: Force unmount is experimental - report any problems.


I found that in rc.d/jail secure_umount() it always do "umount -f "

Maybe it's better first try to unmount without -f and then use force?

    Everything should be made as simple as possible, but not simpler.
