The problem here lies in most cases in the init-scripts, which where
subtly broken to begin with.
I myself had written such init-scripts, which worked well enough while
used by SysV-init, but where technically not correct or did things in a
way that worked on my system but would fail (or create a race condition)
on other systems.
After the switch to systemd those scripts failed on numerous ways and I
cursed at first, but upon closer inspection I saw that they where broken
to begin with and the faulty behavior could also happen with SysV-init.
Fixing those scripts, or, where possible, converting them to native
systemd.units was then the correct solution.
Grüße,
Sven.
