systemd startup issue with generic component name and [install] section

calls like `systemd start dafilesrv` are not working as ops expects and `systemd start dafilesrv@mydafilesrv.service` are returning an issue with the  [install] section missing.

 

[root@System ~]# systemctl enable dafilesrv@mydafilesrv.service

The unit files have no [Install] section. They are not meant to be enabled

using systemctl.

Possible reasons for having this kind of units are:

1) A unit may be statically enabled by being symlinked from another unit's

   .wants/ or .requires/ directory.

2) A unit's purpose may be to act as a helper for some other unit which has

   a requirement dependency on it.

3) A unit may be started when needed via activation (socket, path, timer,

   D-Bus, udev, scripted systemctl call, ...).
