Hi,
As my Pi-Star devices are rarely (if ever) left running overnight I had edited /etc/crontab to run the 'daily', 'weekly' and 'monthly' tasks at time when they are generally running (evenings).
The changes in 4.1.3 mean that this is no longer the case and my changes for the 'daily' cron tasks are now overwitten each time the device boots up.
In fact because I had left the original line in crontab as a comment to remind me what it looked like I get two lines that attempt to do the daily update at the same time.
So I now need to undo the changes and put my 'daily' cron back, but in a manner that doesn't break something else.
