show zfs snapshot properties
                    Hello,
                I once made a snapshot:
# ls -l
-rw-r--r--   1 root     root     3951543392 Jun 19 16:56 sungrid03.snap1
# file sungrid03.snap1
sungrid03.snap1:        ZFS snapshot stream
and I need this file for a restore.
Is there a way so see the properties of this snapshot, because during the restore I need them.
# zpool set bootfs=rpool/ROOT/tank tank
cannot set property for 'tank' : 'rpool/ROOT/tank' is an invalid name
# zpool set bootfs=rpool/ROOT/tank rpool
cannot open 'rpool': no such pool
# zpool set bootfs=rpool/ROOT/s10u9 tank
cannot set property for 'tank' : 'rpool/ROOT/s10u9' is an invalid name
                0
