I believe in order to build the source tree you just need a compatible
toolchain.  So you can build the source tree for 13.0-CURRENT on
12.1-RELEASE system.  But you need CURRENT to **run** userland with ABI
from the CURRENT.

In order to build, for example, 12.1-RELEASE image with release(7) you
should assign the SRCBRANCH variable to "base/release/12.1.0 at rHEAD", and
for 12.0-STABLE: SRCBRANCH="base/stable/12 at rHEAD".  Either in your
configuration file for release(7) or directly in your shell:

env SRCBRANCH="base/release/12.1.0 at rHEAD" /usr/src/release/release.sh

Sure.  Just as a note, by default (when the caller doesn't provide a
configuration file to release(7), or the file provided doesn't exists),
release(7) builds GENERIC kernel and uses no make.conf and src.conf.

Once again: for native build `make release` may be quite easy and fast.
release(7) guarantees "absolutely clean	build environment".

Why not :-)

For me reading /usr/src/release/release.sh and default configs for ARM
saved me a lot of time.
