Question

I have a systemd unit with spaces in an argument

ExecStart=command --argument=\"text text\"

It seems that systemd does not recognize the do

Answer 1

systemd only seems to recognize quotes which fully wrap arguments; i.e.

ExecStart=command --argument="text text"

does not. I just ran into this issue and filed #624 about it.
