+This command will work only if filesystem supports has support for freezing.
+List of these filesystems include (2016-12-18)
+.BR btrfs ,
+.BR ext2/3/4 ,
+.BR f2fs ,
+.BR jfs ,
+.BR nilfs2 ,
+.BR reiserfs ,
+and
+.BR xfs .
+Previous list may be incomplete, as more filesystems get support.  If in
+doubt easiest way to know if a filesystem has support is create a small
+loopback mount and test freezing it.
