It isn't so bad building a flash image for something like this. If you
want to play with it a bit primitively, you can install to a flash
card or a virtual disk configured to have the exact same layout, and
you can mass install to new ones by dd'ing a file system image.
I generally prefer to just bulk install boxes by PXE booting them
though -- less handwork. That requires a bit more work, but any SA
worth his salt knows how to do that sort of thing.
Kickstart and similar tools have taken a lot of the pain out of doing
mass installs, of course. It doesn't matter much if your boot media
are hard drives or 4G flash cards -- it is pretty much the same, you
just need to make sure you're not cramming too much stuff into the
root file system. Hell, 4G used to be a pretty big hard drive, you
don't even have to cram things in too badly if you're running some
sort of Unix-alike...
