Use /var/db/obsolete instead of /etc/obsolete
etc/Makefile:
Create separate target "install-obsolete-files" to populate
/var/db/obsolete, instead of using "install-etc-files".
Makefile:
Add do-obsolete target, to run "cd etc && make install-obsolete-files",
and add this to BUILDTARGETS.
This moves the "obsolete files" creation from "distribution" to "build".
Per discussion with Andrew Brown.
remove dist/*, now that they're not needed.
if MAKEDEVTARGETS is set, use MAKEDEV.wrapper and makedev2spec.awk to
create an mtree specfile containing the devices that would be made with
"etc/etc.${MACHINE}/MAKEDEV $MAKEDEVTARGETS".
otherwise, copy etc/etc.${MACHINE}/MAKEDEV to dev/MAKEDEV (via list.makedev)
- add mtree.common; contains directories used by all images, and optional
entries for dist/*
