TODO:
can log_file be written to?
add systemd unit?

root_relative parameter is not needed, should be able to tell if a path is relative or not by the first character.
gmi.pl needs to accept an arguemnt, where the config.toml is located.

default's root is relative to working_dir which is bad behavior.

remove magic numbers
redirection bug where path = /share/dir, redirection says '30 share/dir/' resulting in '/share/share/dir/'
