Document that the live dump command (`dump -L') creates its snapshot

Browse Source 
in the .snap directory in the root of the filesystem being dumped.
Document that if the .snap directory is missing that it must be
created manually and that it should be owned by user root and
group operator and set to mode 770 before a live dump can be run.

@ -210,9 +210,20 @@ This option is to notify
that it is dumping a live file system.
To obtain a consistent dump image,
.Nm
takes a snapshot of the file system and
takes a snapshot of the file system in the
.Pa .snap
directory in the root of the filesystem being dumped and
then does a dump of the snapshot.
The snapshot is removed when the dump is complete.
If the
.Pa .snap
directory does not exist in the root of the filesystem being dumped,
the dump will fail.
This problem can be corrected by creating a
.Pa .snap
directory in the root of the filesystem to be dumped;
its owner should be root, its group should be operator,
and its mode should be 0770.
