Hi,

Having a ZFS filesystem on root, such that zfs list shows:

zroot  with a mountpoint of LEGACY
zroot/tmp with a mountpoint of /tmp
zroot/usr with a mountpoint of /usr

etc.

How do I create a snapshot of / ?

zfs snapshot zroot/usr@March_10_2011

works fine.. but that snapshots only /usr, not the upper level / right?

Thanks a lot.
Scott
