I have seen the
--no-block argument with systemctl start but I have no idea how to have this in a config (ex.: /usr/lib/systemd/system/dchcpcd.service) or do this with the
systemctl enable command.
If this is explicitly not possible, and I would have to run this in .Xinitrc or the wm (i3 for me) config file with
systemctl start ... --no-block, then my question changes to, how do all the other distributions of Linux deal with this (the 1.5 minute blocking on startup -- I know you can lower it, but that's not the point)?
P.S.: And yeah, obviously this doesn't work:
sudo systemctl enable email@example.com --no-block
