The /usr/src/release that appeared here is just to create a version string.
`make -C /usr/src/release/ -V VERSION VERSION=\$\{REVISION:Q\}-\$\{BRANCH:Q\}` will create a string exactly like 12.2-STABLE, no matter when /usr/src is.

This one of mine is also a reuse of built world.
The main idea of my buildworld, buildkernel, installkernel, and installworld is as follows. (There are some commands mixed in that cannot be executed directly.)
rm -rf -- /usr/obj/{*,.[^.]*,..?*}
git -C /usr/src/ pull && git -C /usr/src/ reset --hard && git -C /usr/src/ clean -dfx
cat somepatches*.diff | patch -Nt -d /usr/src/
cd /usr/src/
make buildworld && make buildkernel
mergemaster -p
make installkernel
make installworld
make delete-old delete-old-libs
mergemaster
reboot
poudriere jail -u -j main # -j name is matched to above command.
poudriere's jail -u will take care of everything from installworld to the /etc installation.
For poudriere-jail, buildworld will not run without -b option.
A copy of /usr/src for jail will be made, but it is required to retain the original source files for jail.
And just to make things a little more interesting...
The jail can be started with the following command.
poudriere jail -s -j main -p default
This jail will be logged in with the following command.
jexec main-default-n env -i "TERM=$TERM" /usr/bin/login -f -p root
This is where you can debug, etc. in a mostly clean environment.
If you break that environment too much, you can use the following command to get it back to normal.
poudriere jail -k -j main -p default
# Regardless of which person's method is more efficient, I am releasing my method in a similar topic area to let people know that there are different types of methods.
Any jails other than -m null will be cleanly removed by poudriere jail -d, so try different ones :)
Regards.
