I decided to do some more test situations to try to figure out how
adding/removing snapshots changes the space used reporting.
First I setup a test area, a new zfs file system and created some test
files and then created snapshots removing the files one by one.
> mkfile 1m 0
> mkfile 1m 1
> mkfil
I really think there is something wrong with how space is being reported
by zfs list in terms of snapshots.
Stealing for the example earlier where a new file system was created, 10
1MB files were created and then do snap, remove a file, snap, remove a
file, until they are all gone and you are left
