Now that we have mksnap_ffs, anyone simulate NetApp's schedule system?

[Tom Limoncelli]

Has anyone written a script to manage mksnap_ffs snapshots similar to 
the way that NetApp does?

(People with NetApp experience know what I mean :-).  The configuration 
is very, um, concice, but it works really well once you understand it.)

I imagine it would be a cron job that would run each hour and 
create&mount a new snapshot if required, or unmount&delete an expired 
snapshot.  Of course, if they used the same snapshot directory names it 
would be easier for users to adapt.

I searched on google and ports and didn't turn up anything.
