Meanwhile I know: My generator was using bash, and for more reliability I
dared to add "set -u". As it turned out my version of Bash has a bug that
causes false reports of unset variables with arrays, so the generator failed
(the thread of handling exit codes of generators). As a consequence of that,
the unit file wasn't created any more (which I hadn't realized at that time).

But still combining the concepts "operation" and "No such file or directory"
is odd: An operation is neither a file nor a directory.

As said in an other thread, the preferred error message is something like
Failed to execute operation: blabla not found", where "blabla" is the unit in
question.
