I did say it was kludgey, but it might not be a bad idea for updatedb
to only index disks that were system-mounted ("permanent"?), disks
anyway and use the NETWORK feature for any smb mounts one wants to
index...

"Should" != can. Tried that but the mirror I was using apparently wasn't
carrying source packages and displayed "n/a" when I clicked on source.
I just have to look a bit further to find a mirror that does have them,
but sounds like source won't do me much good

I've never been able to get the cygwin source to compile w/o errors, so it
might not be trivial for me. Seems like the last few times I tried it, it
complained about some include file or another missing....just don't have
all the proper pre-req's loaded I guess -- is there a pre-req list
somewhere?
