That's what I do.  I have an unblemished area into which I sup from the
net.  I have a separate directory tree where I do my builds and
modifications; this gets union-mounted over the real source when I'm
doing work.  It gets unmounted before I start sup up, lest the sup gunk
squat on my own files.

I use plain RCS on my own local mods, which are small enough for me to
manage that way using manual merges with 'co -jlast-sup:this-sup -l
file.c'
