$ man bootup

you can create unit files with "After=" and "Before=" to sort yourself into the bootup sequence.

For /etc/rc.local there is /lib/systemd/system/rc-local.service, which executes /etc/rc.local, if it exists. It is ordered "After=network.target".

Comment 3 Harald Hoyer 2013-06-27 11:03:08 UTC
To see what happens, remove "quiet" from the kernel command line, or inspect the journal after booting.

# journalctl -b

Comment 6 Hans de Goede 2013-08-06 13:41:44 UTC
As explained already in comment #2 you can create unit files with "After=" and "Before=" to sort yourself into the bootup sequence.

We also still support rc.local, but only for compatibility reasons, the rc.local support is deliberately not advertised in the systemd documentation, since we discourage its use.

The systemd documentation in general does not document deprecated compatibility mechanisms to avoid promoting the use of them, ie it also does not document that the service and chkconfig commands can still be used.
