32# The default syslog implementation should make syslog.service a
33# symlink to itself, so that this socket activates the right actual
34# syslog service.
35#
36# Examples:
37#
38# /etc/systemd/system/syslog.service -> /lib/systemd/system/rsyslog.service
39# /etc/systemd/system/syslog.service -> /lib/systemd/system/syslog-ng.service
40#
41# Best way to achieve that is by adding this to your unit file
42# (i.e. to rsyslog.service or syslog-ng.service):
43#
44# [Install]
45# Alias=syslog.service
46#
