Done Inline Actionsthat's indeed necessary; as we might take care about output's compatibility here.
the outputs for what -qs /boot/kernel/kernel are documented here on a previous comment;

Done Inline Actions^12 is wrong though. But more importantly, the problem here isn't stable vs release. It's reproducible build vs not reproducible build. You should be testing more directly for that in the output rather than using this heuristic that just tests for environments where reproducible build was yes vs no. imp: ^12 is wrong though.
What about FreeBSD 11?

Done Inline ActionsI would like to flag one little thing still; should we've being talking about WITH_REPRODUCIBLE_BUILD. newvers.sh do produces a kern.version that is used as base for us here to format our verbose output. taking the example of a recent FreeBSD CURRENT we have the following: egypcio@gaz:~ % sysctl -n kern.version
FreeBSD 14.0-CURRENT #11 main-n257521-97be6fced7d: Sat Aug 20 11:07:35 UTC 2022

FreeBSD 14.0-CURRENT #11 main-n257521-97be6fced7d: Sat Aug 20 11:07:35 UTC 2022based on what the newvers.sh does, sysctl -n kern.version | head -1 is pretty much what one gets by default, should reproducible builds are enabled; and that's exact the same (reproducible) output as we do get from what -qs egypcio: I would like to flag one little thing still; should we've being talking about… | |||||

Done Inline ActionsFor these two, consider just building the string then outputting it: out=$(sysctl -n kern.osrelease)
[ $progverbose -gt 0 ] && out="${out} $(sysctl -n kern.osreldate)"
echo "$out"In these cases, the main purpose is making it trivial to understand upon inspection that the first column remains constant between -v and normal invocation. It also reduces duplication in doing so. kevans: For these two, consider just building the string then outputting it:
