Yeah, I'm not sure how best to handle this either, but I'd suspect most
of the NFS related servers would be bound together by a target of some
sort (nfs-server.target?) I've not looked but that would be my guess as
to how it would work. Then each of the required parts of an nfs-server
can have .wants links shipped in the package (e.g.
/lib/systemd/system/nfs-server.target.wants/nfs-rquotad.service).

Of course if these sub-components are optional pats of an "nfs server",
then they shouldn't have symlinks shipped in the package. The ones we
want to "enable by default" should be enabled in a %post script when the
package is installed *for the first time* and by a %triggerun of the
version that they were removed to handle upgrades (see systemd package
for example of this).

As these sub components should all have their install section with:
[Install]
WantedBy=nfs-server.target

All you should need to do to migrate sysvinit to systemd is to look for
the enabled sysvinit scripts and enable the nfs-server.target (the
target unit itself should contain an install section that means it's
WantedBy=multi-user.target.


But I've not really looked at the Fedora units or our nfs package since
these updates so take the above as a general comment only :)

Cheers
