OK, so I just have to mass-generate a load of cygport packages and then
maybe bundle them into an umbrella package with no content of its own,
but make that dependent on all the others so I don't have to specify all
of them for installation.  Fair enough, just not as easy as I hoped.

Most users will never see the chooser window anyway, so it's probably
OK either way.

I've had to try it today, and it seems that appending something
alphanumeric (like -2p1 for the first patch on release 2) is OK with
setup.exe (don't know yet what genini thinks of that, though).

You've lost me here, where does that PATCH_URI you are talking about
belong?  The packages I've looked at had at most two patch files (for
the source and for cygwin specific additions) that are seemingly used
automagically.  Not that I looked at a lot of packages...

Not sure yet, but basically anything that can't be solved by simply
dropping a file in the right place and that isn't associated directly
with a package being installed or de-installed.

I think I can fake it with the current setup.exe (I already install the
snapshots this way).
