Re: Install script supporting sysV init?

[Jan]

Thanks, this generally works, except this line:
> GUIX_LOCPATH=/var/guix/profiles/per-user/root/guix-profile/lib/locale
> -E LC_ALL=en_US.utf8 -p /var/lock/guix-daemon.pid guix-daemon
While trying to start the daemon, daemonize complains about the path
not being absolute.
I changed "guix-daemon"
to
"/gnu/store/ncknl03pkmamrxg7q9nxi1rn1qhvwbi9-guix-1.0.1/bin/guix-daemon"
and it worked, but it isn't the right solution I guess. What should I
do?
