I can't say that I've tested the sysvinit version of docker for quite
some time, so it very well could have some bitrot.

I do run the systemd version though, and haven't been having any issues.

Taking a look at things, I can see that yes, it should be dockerd and
the sysvinit variant has rotted. The confusion around the systemd one
is that the service file in the layer is no longer used, and is also
out of date. We use the docker.service file from the source repo
itself, and it has the correct daemon startup.

Did you want to submit a patch to update the sysvinit startup script ?

I'll cleanup the invalid/old systemd one, but since you are in a
position to test the sysvinit one, it would be better if you could do
it.

Cheers,

Bruce
