We do have such a partition already: /dev/hda2 is an (unformatted) 16MB scratch partition protected from being clobbered by upgrades.
I never really looked at that, I figured that it was the scratch and the OPUS fs partition was a backup of the critical files. Good to know I can use it. On mine it's showing 32 megs of space there.
Oops, right. Minor unit identity crisis; sorry -- it is 32MB.
That's what archives are for :-)
I will put an archive up on the developer site, eventually. :-)
