I'm not sure what you're referring to here -- when I type snap -a, I
get no output back.

I'll read the fossilcons manpage on this again and see what the usage
of this is. I guess I am somewhat worried, simply because I don't want
to fill my fossil partition (I still have > 35GB data to copy over)
and have it blow up.

At this point, I think I've probably munged what's in Venti enough
that I'm going to go ahead and reinstall with this `newfound'
knowledge.

Thanks for the information -- I'll definitely try it out this time.
