If I may make a little comment here.
Surely it is a little bit questionable to "bake assumptions" into sysupgrade
that everybody is going to do a complete install when the OpenBSD installer
itself gives you the option to select what is going to be installed.
At the very least, may I suggest that even if the developers don't want to
increase the intelligence of sysupgrade that they at least code in some sanity
checks (e.g. "pick a file - or two - at random from the core tgz files that you
would normally expect to be present on the system if a 'full-default' install
was done. If file not present, then throw a horrid error message and abort).
It strikes me as a little silly to put a tool out there that you know will
trash (or at least severely brick) a user's system just because of some
severely opinionated "baked assumptions" coded into it.
