Trigger a restart of the post-resume.target on resume.
That allows other systemd services to receive the restart signal
after resume by becoming 'partOf' the post-resume.target.
The build can loop forever generating an infinite amount of log data,
filling up Hydra's disk:

Building emPdf failed, but that project is not so essential.
So if you don't know how to solve the problem, then you could
continue the overall building now, and live without the features
the project provides. Continue? [y(es)/n(o)/a(lways)]: Use of uninitialized value $ln in pattern match (m//) at make.pl line 626.
