Hi Thomas,
RuneAudio is based on Arch Linux.
Arch Linux uses systemd to start services, so /etc/rc.local doesn't exist.
To fix that, just edit the file /usr/lib/systemd/system/rc-local.service:
[Unit]
Description=/etc/rc.local Compatibility
ConditionPathExists=/etc/rc.local
[Service]
Type=forking
ExecStart=/etc/rc.local start
TimeoutSec=0
StandardOutput=tty
RemainAfterExit=yes
SysVStartPriority=99
[Install]
WantedBy=multi-user.target
Create the /etc/rc.local script and make it executable with
chmod +x /etc/rc.local
After that you have to enable this service:
systemctl enable rc-local.service
