@pichlo Thank you very much for reporting this issue.
I found the bug, it is the console reader in gpscon which was causing the cron problem.

You can stick to the gpscon-0.0.4-1.armv7hl.rpm version to solve the problem or wait for a new version.

The latest version on openrepos gpscon-0.0.8-1.armv7hl.rpm will not fix the problem it was a test version about the argument parser, but the next version will correct the console reader for sure.
