I think systemd messed up the start up order of the net service. I have to restart net.eth0 whenever I reboot in order to get internet connection. How do I view and change the order in which services start up with systemd?

How do you manage to restart net.eth0 if OpenRC is not running? 8O

To have network, you need to make sure the dhcpcd.service and the network.target are enabled.

Code:
$ systemctl status network.target dhcpcd.service
network.target - Network
     Loaded: loaded (/lib64/systemd/system/network.target; enabled)
     Active: active since Tue, 06 Dec 2011 22:09:28 -0500; 11h ago

dhcpcd.service - Lightweight DHCP client daemon
     Loaded: loaded (/lib64/systemd/system/dhcpcd.service; enabled)
     Active: active (running) since Tue, 06 Dec 2011 22:09:28 -0500; 11h ago
   Main PID: 2002 (dhcpcd)
     CGroup: name=systemd:/system/dhcpcd.service
        └ 2002 /sbin/dhcpcd -q --nobackground

I just ran /etc/init.d/net.eth0 restart, it does the trick every time, so I figured that was it. :-P

Anyway, the network.target is dead.
Code:

ron $ systemctl status network.target dhcpcd.service
network.target - Network
     Loaded: loaded (/lib/systemd/system/network.target)
     Active: inactive (dead)

dhcpcd.service
     Loaded: error
     Active: inactive (dead)

Both, network.service and dhcpcd.service don't exist apparently, but they do show up in systemadm.
Code:

root # systemctl start network.service
Failed to issue method call: Unit network.service failed to load: No such file or directory. See system logs and 'systemctl status' for details.
root # systemctl start dhcpcd.service
Failed to issue method call: Unit dhcpcd.service failed to load: No such file or directory. See system logs and 'systemctl status' for details.

What do I do?

I have dhcpcd installed, it's just I could never get internet connection working without a static IP.
Code:

root # emerge --pretend dhcpcd

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild   R    ] net-misc/dhcpcd-5.2.12

Can someone point me to a manual for systemd? The man page is nothing special. Instructions on setting up/writing my own services would be godsend.

systemd comes with by far more that one manpage :wink: Anything you need should be there. You should be particularly interested in "systemd.unit" manpage and "systemd.service".

This should also be useful: http://0pointer.de/blog/projects/systemd-for-admins-3.html

Also, despite popular preconceptions, you can use service files to launch shell scripts, if needed.
