This seem pretty obvious solution and it will work in most of cases. But
there are caveats though. What comes to my mind:
* /etc/make.conf vs. ${DESTDIR}/etc/make.conf issue (that's also
important with real DESTDIR). This can't be resolved easily -
if DESTDIR is jail, it's likely that /etc/make.conf is need, but if
remote system is mounted over NFS, ${DESTDIR}/etc/make.conf is to be
used.
* It was mentioned already, I'll second: I don't trush nullfs much :)
* Both current and nullfs-drived DESTDIR implementations require all
depends in the DESTDIR. But actually BUILD_DEPENDS from host can be
used.
I had also thinked over an idea of package-driven DESTDIR
implementation. Like automated building packages on the host system and
then installing them into DESTDIR.
No nullfs, no makefile dualism, no need to change ports, small amount of
changes to Mk/, BUILD_DEPENDS don't get installed into DESTDIR. But, no
support for cross-builds.
