+Resizing, shrinking, specifying sizes in guestfish
+--------------------------------------------------
+
+Owing to an oversight we don't really supporting shrinking
+filesystems.  See:
+
+https://bugzilla.redhat.com/show_bug.cgi?id=585221
+https://bugzilla.redhat.com/show_bug.cgi?id=585222

+
+But a related problem is how to specify sizes to guestfish, ie. "100M"
+or "1G".  Currently the specific alloc and sparse functions contain
+code to parse these size strings, but that cannot be used anywhere
+else that would take a byte count.  This is awkward because some
+commands take units of megabytes (lvresize, sfdiskM) or sectors
+(part-add), with no unifying theme.
