Shortest source update requirements.

[MG]

I lost track of how gitup works or it has changed and no longer works in my build chroot. I don't like spending time on this. It tries 15.0 on a 15.1 kernel... What's the most simple way to get the latest FreeBSD 15.1 source tree?

If you are running pkg base, install the relevant pkgs (src or sys only).
The upside is that it will always match the running kernel, the downside is that if you are on stable/current there's a lot of churn.

If you want to use gitup for this, edit /usr/local/etc/gitup.conf and replace "branch" : "releng/15.0", with "branch" : "releng/15.1", (this is under the top level "release" entry) and then do "gitup release".

Install one of the following devel/git flavors, listed by number of dependencies. Top listed: most, bottom listed: least.

git        Distributed source code management tool
git-lite   Distributed source code management tool (lite flavor)
git-tiny   Distributed source code management tool (tiny flavor)

List dependencies: pkg rquery %dn <git_flavor>

Proceed with FreeBSD handbook, 27.7. Updating FreeBSD from Source, chapter 27.7.3. Updating the Source:

# mv /usr/src /usr/src.bak
# git clone --branch releng/13.2 https://git.FreeBSD.org/src.git /usr/src

Obviously replace unsupported version from the handbook example with a supported version.

# mv /usr/src /usr/src.bak

This might not work if you have a ZFS system, /usr/src/ is a separate dataset and you cannot rename it this way. I'd just nuke it, no reason to keep a 'backup' of it, rm -rf /usr/src/* /usr/src/.[^.]*
