1. Provide a consistent and extensible framework for compiling
kernels for the "make snapshot" target.
2. Add OBJDIR support for the "make snapshot" target, in the form
of three new make variables: KERNOBJDIR, KERNSRCDIR, and KERNCONFDIR.
Default values are in the Makefile.inc, and for OBJDIR they should
be defined in /etc/mk.conf as
KERNSRCDIR=${BSDSRCDIR}/sys
KERNOBJDIR=${BSDOBJDIR}/sys/arch/${MACHINE}/compile
The next step is to make a new target in the src/etc/Makefile for "release"
(or something like that) to make release(7) format files.
* remove superfluous umasks
* replace `eval ...` with $((...)) or ${i#...}
* use $0 instead of MAKEDEV
* warn on unknown devices
* add enss* to ss*
* ensure tapes are root.operator 660
Tape devices now called after their kernel names, (ie. ts0, ht0) and
not mt? for all of them. mt? names are kept as symbolic links anyway
so that it don't break anything.
