Really, systemd's "pretty decent compatibility with sysv initscripts" is
overrated.

systemd sysV ordering depends on LSB sysV headers that where essentially
*ignored* in Fedora. Most historical Fedora sysV services relied *only* on
service number to get started in the right order. Even if they had some LSB
stuff in, it was completely untested (just look at how the sysV services are
labelled in systemd, clearly no one even checked the service descriptions
before and that's *simpler* than getting deps right).

Since systemd ignores those numbers as soon as there is something looking like
an lsb dep in the service chain (that may have been put in as an experiment
years before, or as a cut and pasted boilerplate the maintainer didn't care
about), a lot of Fedora sysV scripts are *not* compatible with systemd unless
rewritten in LSB dependency style.

So what is the point of effectively rewriting existing sysV services in a new
sysV dialect now (to rewrite them again next release as native systemd units)
instead or rewriting them directly as systemd services? In both cases there is
a high risk of regressions as dependency logic was not tested before. Except
that systemd works better with native units, so I'm far from sure the less
risky path is to try to "fix" sysV services so they semi-work.
