Ok, I'll try a test:

    root@cufic:~# aptitude purge initscripts
    The following packages will be REMOVED:
       initscripts{p}
    0 packages upgraded, 0 newly installed, 1 to remove and 7 not upgraded.
    Need to get 0 B of archives. After unpacking 213 kB will be freed.
    Do you want to continue? [Y/n/?]

    ... it boots up ...

Seems it wasn't run 'cos rc.local doesn't exist.

Make a rc.local:

    root@cufic:~# cat > /etc/rc.local
    #! /bin/sh


    # Test rc.local


    echo Hello from rc.local


    exit 0
    ^D

    root@cufic:~# systemctl reboot


    ...


    ... it boots up.

So, it looks to me if /etc/rc.local exists and is executable then
systemd runs it as I thought.

If it didn't work for the bitcoin guys then the problem is somewhere else.

(Damn but the systemd journal is great :-))

Come to think about it, if the problem was that their rc.local was
failing somewhere then they should be able to see that in the output of
systemctl or journalctl.

Assuming they're using systemd, of course.  :-)
