Suggestion for a HAMMER feature

[Petr Janda <elekktretterr@xxxxxxxxxxxxxx>]

Hi guys,

Being forced to use Solaris and ZFS, I found a few, what seem to be easy 
things to add to Hammer:

1) Make df -h list show how much space is used by each PFS
2) Make df -h show how much space is taken up by historical data and how much 
is taken up the the "current" data and combined.
3) in hammer info show how much historical data is being stored.
4) Maybe an equvalent of "zfs list" ?

Would these be simple to add in?
