[44net] ipip.routes and rc.local

More of a Linux question, but worth a shot since others have probably been to this rodeo before. I have come across an issue starting AMPRnet automatically at boot. The ipip.routes script seems to fail starting the tunl interface when ran by the system by the rc.local script. Interestingly, when ipip.routes is ran in the crontab (nightly update) there are no issues. So this is specifically related to the rc.local script. Anyone else run into this issue? Thanks, Assi kk7kx
