Summary

Using these targets on a pkgbase system will cause the installed system
to become out of sync with the package database, which is almost certain
to cause issues the next time pkg(8) is used.

To prevent users doing this accidentally, disallow install* if we detect
that FreeBSD-runtime is installed in the target. The check can be
overridden with DESTDIR=/ for users who are sure they want to do this.

I see the rationale for this as an anti-foot-shooting device, but I'm not sure if the FreeBSD user community is ready for this yet.

I'm inclined to either make this switch in 16 or email freebsd-current to solicit feedback first.

Looks like a reasonable safeguard.

I could see this tripping up folks, but just as easily I can imagine someone using pkgbase, then installworld over top and complaining about a mixed-up installation.

While I was initially an objector to this and am not a big fan of BASIFY. This seems like
a reasonable compromise that is easy enough to tool around. So as to keep current work
flows working w/o too much disruption. Thank you for taking the time to make this work
for everyone. :-)

i posted about this on stable@ and current@ a week ago and no has objected, so i'd really like to land this if possible.

right. the difference is in the first case, the user just needs to learn the right way to do this dangerous action, in the second case the user ends up with a broken system with no warning. i think the first case is much preferable, because while this might mildly annoy users, the second case will be much more annoying :-)

and let's be clear, someone is going to do this by accident, and then complain that pkgbase broke their system... and they won't be entirely wrong about that if we let them do this.

1370	Can we add some `I_KNOW_WHAT_IM_DOING` override here, to make it still possible to run `make install{world,kernel}` on a pkgbase'd system?

1370	I should've probably try reading the error message first. Sorry for the noise.

Makefile.inc1
590	A little unfortunate that this is decoupled from the other pkg variables. Maybe move the rest of them up so they're still grouped with the `.if make(package)` in the middle of them?
1372	Maybe `${.TARGET} should not be used`?
