RedPit WSPR Transceiver changing from Debian to ALPINE

Yesterday I started changing from RedPitaya DEBIAN Linux system (Pavel) to his new ALPINE based system.
Main reason is that with the last Debian WSPR release an incorrect shutdown always leads to a file crash killing the complete SD image.
So I always had a back-up SD cart prepared.

Firstly it seems to be easy to change but I have a 5W PA from QRP labs and a 5 band filter bank. All switching is done by the RedPit GPIO and a relais board from QRP LABS. And here was the problem since the CRON tab is handled in a different way.

So currently it seems to work 90% but some more work to do...
