Bug#794050: udev: initramfs-tools-hook fails with: find: '/etc/systemd/network': No such file or directory

[Dirk Griesbach]

Package: udev
Version: 223-1
Severity: important

Hello,

Installing 223-1 leads to the following error message:
,----

The hook in question changed behaviour from udev 222 to 223 where the
explicit test for directories /etc/systemd/network and
/lib/systemd/network to copy *.link files was replaced by a non
conditional find. The latter fails as at least /etc/systemd/network is
not present on (my) sysvinit-powered systems.

Thanks,
Dirk
