fine with me, but then the commit message should be adjusted to reflect this

Ah yes I read it to quickly, I thought it meant logging to gsmtap also meant logging to stderr. In any case, IMHO it is kind of obvios that you configure each log target independently, and then this kind of announce should be put in each other log target section. So I think it's best to drop it. The "force-all" stuff is already covered further above in the file.

Change subject: ttcn3-bts-test: add --no-warnings to bpftrace
......................................................................
ttcn3-bts-test: add --no-warnings to bpftrace
Since switching to debian 13 and having bpftrace 0.23.2 instead of
0.17.0, bpftrace is constantly printing warnings. Turn off warnings by
default so we don't end up filling up the disk space of jenkins runners
while ttcn3-bts-test runs for >2h.
We can turn on warnings in copies of the main jenkins job for
development, while also ensuring that we only run a few tests instead of
the whole testsuite.
Warnings look like this:
root@deb12build-ansible:/home/osmocom-build/jenkins/workspace/ttcn3-bts-test/logs/bts/bpftrace# head udp_sendmsg_delay.log

yes, these warnings (all complaining about tid being invalid it seems) are printed over and over again, filling up the disk until it is full:
