<para>It is important to distinguish "linked unit files" from "unit file aliases": any symlink where the
symlink <emphasis>target</emphasis> is within the unit load path becomes an alias: the source name and
the target file name must satisfy specific constraints listed above in the discussion of aliases, but the
symlink target doesn't have to exist, and in fact the symlink target path is not used, except to check
whether the target is within the unit load path. In constrast, a symlink which goes outside of the unit
load path signifies a linked unit file. The symlink is followed when loading the file, but the
destination name is otherwise unused (and may even not be a valid unit file name). For example, symlinks
<filename index='false'>/etc/systemd/system/alias1.service</filename> → <filename index='false'>service1.service</filename>,
<filename index='false'>/etc/systemd/system/alias2.service</filename> → <filename index='false'>/usr/lib/systemd/service1.service</filename>,
<filename index='false'>/etc/systemd/system/alias3.service</filename> → <filename index='false'>/etc/systemd/system/service1.service</filename>
are all valid aliases and <filename index='false'>service1.service</filename> will have
four names, even if the unit file is located at
<filename index='false'>/run/systemd/system/service1.service</filename>. In contrast,
a symlink <filename index='false'>/etc/systemd/system/link1.service</filename> → <filename index='false'>../link1_service_file</filename>
means that <filename index='false'>link1.service</filename> is a "linked unit" and the contents of
