Comment # 1 on bug 1045396 from Dominique Leuenberger

The 13.1 disk image, before updating, has:

systemctl status network.service
Loaded: loaded (/usr/lib/systemd/system/network.servicel enabled)

rpm -qf /usr/lib/systemd/system/network.service
sysconfig-network-0.81.5-30.1.x86_64

After updating that disk image to snapshot 0619, we get:

systemctl status network.service
Loaded: loaded (/usr/lib/systemd/system/wicked.service; enabled: vendor preset:
disabled)

There is a symlink in /etc/systemd/system/network.service to wicked.service

When updating this snapshot further to 0620, network stays operational.

Then I tried to update the base disk image to 0620 directly - and that resulted
in no network again (systemctl status network.service gives service unknown)
