+2021.0227 osx fixed gdf
+
+2017.1228 switched make-snapshot order to have ex. "Wed" after DOM to avoid snapshot rollback "newer exists"

+
+2017.1229 DONE zfs-list-snaps instead (shows creation date
+DONE save space in log - when listing snapshots, only list relevent-day
+DONE enumerated stages better (for searching
