<para>Various settings are allowed to be specified more than once, in which case the
interpretation depends on the setting. Often, multiple settings form a list, and setting to an
empty value "resets", which means that previous assignments are ignored. When this is allowed,

<para>Units can be aliased (have an alternative name), by creating a symlink from the new name
to the existing name in one of the unit search paths. For example,
<filename>systemd-networkd.service</filename> has the alias
