Run script on boot

[luis84]

Cant Reboot (while sleep script WOL)

Sounds pretty crazy that the referenced script logs into flash every five seconds But that is just wiki advice... It might make sense to run the periodic check script from a detached shell, so that it would certainly not block any further script evaluation. E.g like this: ( /path-to-script/script.sh )&

maybe there are problems with sshpass
