However, it takes the same amount of time as without reuse, and the

behavior, and if so - what can I generally expect from
reuse_scan_results?

It's normal.  Re-using scan results will improve performance if there aren't
many changes, but for example devel/gmake was touched in the last few days
and that will cause pretty much everything to be recomputed, and you won't
see any difference in runtime.

Actually, touching a pure tool doesn't force a rescan, but touching
something in pkgsrc/mk/ like bsd.prefs.mk will certainly force
everything to be rescanned.

Strictly speaking, I feel that the re-scan is also taking place even though I have not made any changes to the entire pkgsrc directory.

I use a limited_list and saw in /usr/pbulk/libexec/scan that there is a case distinction here - depending on whether the variable is set or not. Can this have something to do with it?

Kind regards
Matthias
