In DMD, the "respawn.sh" test fails quite consistently on armhf, and has
sometimes failed on mips64el and x86_64 as well. Here's a copy of
test-suite.log from a recent failure on armhf:

The problem here is that the PID file for ‘service1’ is not ready when
we ‘test -f’ it right after ‘deco status test1’ has told us the service
is started. That’s because there’s a small window during which the
service is started but has not created its PID file yet.
Fixed in dmd commit f33f81f.
We’ll backport it in Guix or make a dmd release.
Thanks,
Ludo’.
