So I run these commands?

rm -fr /usr/src
gitup release

cd /usr/src
make buildworld
make buildkernel

make installkernel
etcupdate -p
make installworld
etcupdate

Or I don't need "etcupdate -p" ? In
https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html
<https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html>
I don't see that "mergemaster -p" is needed and I don't
remember where I found this command but I use it for a long time.

I found the "mergemaster -p" in an older doc version:

mergemaster -p :

This does some initial configuration file updates in preparation for the new
world. For instance it may add new user groups to the system, or new user names
to the password database. This is often necessary when new groups or special
system-user accounts have been added since the last update, so that the
installworld step will be able to use the newly installed system user or system
group names without problems.

But the latest doc version has no reference about "mergemaster -p".

So "mergemaster/etcupdate -p" is not needed if we use 12.2?
