Not sure if it is related, but I noticed that we are also rebuilding a
lot of files in the gitlab-CI that we did not before the meson
conversion, especially in the check-system-* jobs, e.g:
https://gitlab.com/qemu-project/qemu/-/jobs/977344949#L366
The check-system-* jobs should normally take the artifacts from the
build-system-* jobs and thus hardly recompile anything at all.
A part of the problem seems to be that we check out the submodules
again, I can get rid of the superfluous reconfiguration step by adding
something like:
Yes, there's a
[0/1] Regenerating build files.
/usr/bin/python3: can't open file
'/builds/qemu-project/qemu/meson/meson.py': [Errno 2] No such file or
directory
because the submodules have not been checked out, and that causes meson
to run again.

could that be related to that meson problem, too?
No, I think it's just that, after the new checkout, the source files'
timestamps should be quite new and cause everything to be rebuilt.
