Again - this has improved in current version which now tells you that
unit is generated.

Targets are allowed to be generated but generated units cannot be
enabled/disabled. The rationale probably is that if you create unit file
you can just as well create symlink to this unit file. Also "systemctl
dameon-reload" removes and re-creates all generated units, so any
symlink to such unit outside of generated subdirectories potentially
becomes invalid.

Documentation could be better indeed.
