On a serious note, what I'd change about FreeBSD hier(7)

Same here.  I have a single FreeBSD machine in an ocean of NetBSD and
Linux so every now and then I'll install something without stopping to
recall that I'm on the FreeBSD machine.  It hurts every time to undo
the installation, especially when what was installed collided with
an installed port.

Maybe I should write a make wrapper that detects whether I'm in
/usr/local and goes Abort, Retry, Ignore?...
