This depends on the program you are invoking as a service. i.e. ask
the folks who wrote "ifmand" about this, or consult the documentation
for that program.

When systemd cannot invoke a program you configured it will generate a
couple of error codes on its own. These are documented here:

https://www.freedesktop.org/software/systemd/man/systemd.exec.html#Process%20exit%20codes

But as you can see there 251 is none of the exit codes systemd itself
defines, hence it must come from your own app.
