[PATCH 1/1] systemd.class - Allow enabling of parameterised services

[Bob Ham]

Currently the systemd.class will check whether a service exists when
it is requested to enabled it.  However, its check does not take into
account that a service like 'foo@eth0.service' can be enabled from a
service named 'foo@.service'.  This patch alters the check function in
systemd.class to look for 'foo@.service' if the normal check fails.
