Using variables in systemd unit file
1
I want to use a variable in a unit file. Note, I do not want an environment variable, as I do not want the variable to be visible in the service. I just want to minimize redundancy in the unit file. eg,
I'd like to do something like:
[Service]
Type=simple
Variable=path=/usr/local/somepath
ExecStart=${path}/bin/executable -c ${path}/etc/blah.cfg
Can this be done without resorting to sh -c "path= $path/bin/executable ...." with an Environment directive?

No-one has yet mentioned macros, though, to my knowledge. (-:

Thanks for the refs. Every question I looked at immediately started talking about environment variables, and I stopped looking too soon.
