The unit files have no [Install] section. They are not meant to be enabled<\/span>
using systemctl.<\/span>
Possible reasons for having this kind of units are:<\/span>
1) A unit may be statically enabled by being symlinked from another unit’s<\/span>
\u00a0\u00a0 .wants\/ or .requires\/ directory.<\/span>
2) A unit’s purpose may be to act as a helper for some other unit which has<\/span>
\u00a0\u00a0 a requirement dependency on it.<\/span>
3) A unit may be started when needed via activation (socket, path, timer,<\/span>
\u00a0\u00a0 D-Bus, udev, scripted systemctl call, …).<\/span><\/p>\n
