Package: udev
Version: 204-8
Severity: important
Tags: patch
Actually the bug is related to systemd but should be fixed in udev IMO.
If a network device contains a '-' character, ifup is not executed by
systemctl (systemd service) and therefore setup of the device fails.
The character might trigger a conflict because it is used as separator
for device hierarchy, as shown in this example:
Device name: veth-devmachine
Syslog entry #1: systemd[1]: Expecting device
sys-subsystem-net-devices-veth-devmachine
Syslog entry #2: Starting ifup for veth/devmachine...
Tests show that systemctl with unit /lib/systemd/system/ifup@.service
is the failing step in the execution chain.
It looks that '-' in fact is special to systemd and must be avoided.
Then an error message is essential, because the device naming works
with other startup systems and in the scope of networking that kind of
dependency is not ... er ... obvious.
The attached net.agent-systemd.patch fixes this.

Gero
