dirs forgotten all around. One can still unset it in /etc/mk.conf to get
back to the older behaviour, or still override it with /usr/obj/ports or
/usr/wobj or whatever. At least, now it can be a separate partition.
Most of us were already overriding this value, OpenBSD is all about sane
& simple default settings.
${PORTSDIR}/obj suggestion from jakemsr@.
Discussed at length with several, 'Works for me' krw@ ok todd@ wcmaier@.
