Failed to parse content of the file '/proc/cmdline'
Foris controller repeatedly writes to the system log:
ERROR:foris_controller_backends.files:Failed to parse content of the file '/proc/cmdline'
It occurs both on a system installed from another versions via switch-branch and on a cleanly installed system (from a medkit).
Affected versions: 5.1.0 and newer (possibly older versions too but not tested)
