Description Ivan Rozhuk 2023-10-01 03:36:24 UTC 
sys/conf/newvers.sh -R KERNEL_CONFIG_NAME
and
make -C release -V BRANCH
called during build kernel and wold.
Both call git if it installed and does not fail if there is no git or .git repo.

NOGIT='yes' does not stop this.

As workaround I use:
GIT_CMD='/dev/_not_exist_'
helps with (release/Makefile.inc1)
and
svnversion='echo'
sed -i '.orig' -e 's|local savedir|return 1|g' "sys/conf/newvers.sh"

Is it possible to make NOGIT=yes work for whole build process?

Certification for product procedure requires provide list of all files that was used during build.
My manager wants to minimize that list and do not want provide .git files.
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=274198 also as part of this work.

newvers.sh looks for a .git directory and does not invoke git if not found.

I do not want workaround with renaming git binary or renaming .git dir, I want NOGIT or similar knob start work.

Also "auto detect" features without on/off switch produces unpredictable results, so REPRODUCIBLE_BUILD is not reproductable: newvers.sh give different output on systems with .git+git and on systems without it.
