[systemd-devel] systemctl enable myunit.service ---> Failed to execute operation: Invalid argument

[bobafetthotmail]

Finally found a workaround, bypassing systemctl.

I'm making myself (having the script autoinstall routine do, actually) 
the symlink that systemctl refuses to make, as that's the only thing 
that "systemctl enable XXX.service" seems to do.

ln -s /etc/folder2ram/folder2ram.service 
/lib/systemd/system/local-fs.target.wants/folder2ram.service

(from the service file wherever it is, to the folder of the target 
stated in "WantedBy=foo-bar.target" in the install section)

Ran some tests, and my script is indeed called on startup and shutdown, 
no error reported anywhere.

So this issue was confined to systemctl (thankfully).
