As observed in "Build test / distcheck (pull_request)" of #2963.
I may have to backport some changes from #2952 semantically.

@karelzak Please assign this to me.

The following error was reported as the result of rpm-build:fedora-rawhide-aarch64 in #3063. It had nothing to do with the change proposed in the pull request.

I wonder the error was something to do with this issue.

lsns/filter test case failed on rpm-build:fedora-rawhide-ppc64le (#3105).

Manually formatted log:

We can know that lsns didn't report PID.
We need more information for debugging.

  • the exist status of lsns
  • debug-enabled output

I will make a pull request.

At #3205, I can constantly reproduce the failures of the lsns/filter.
