1338 " wants to run 'reboot' at this point to cause the system to reboot.\n" \

1340 " init is told to reboot. Unmounting filesystems and disabling swap\n" \
1341 " is a very good here\n" \
1343 " Run repeatedly actions:\n" \
1345 " 'respawn' actions are run after the 'once' actions. When a process\n" \
1346 " started with a 'respawn' action exits, init automatically restarts\n" \
