For example smbd/nmbd:

smbd has:
After=network.target nmbd.service winbind.service
nmbd has:
After=network-online.target
Wants=network-online.target

But in syslog I've seen smbd occasionally starting before nmbd,
and nmbd often starting before network was fully up - i.e. before dhcp
handshake was complete.

I had really problem getting my own script to run
After=network-online.target and Before=smbd.service (samba-ad-dc)

Now I managed to get it run ok, but I'm not 100% sure if it is reliable
or just a good luck and coincidence.

My script has:
After=network-online.target
Wants=network-online.target
Before=zfs.target
WantedBy=zfs.target

and samba-ad-dc has:
After=network.target
After=zfs.target

I thought I could get inspiration from distro provided units like smbd
and nmbd, but even they did not behave as expected.

I suspect there might be a problem parsing multiple arguments on single
After/Before line, or that it works only with *.target, but not *.service.
