# 0 - file system is unmounted and okay
# 32 - file system is unmounted and needs checking (fsck -m only)
# 33 - file system is already mounted
# 34 - cannot stat device
# 36 - uncorrectable errors detected - terminate normally (4.1 code 8)
# 37 - a signal was caught during processing (4.1 exit 12)
# 39 - uncorrectable errors detected - terminate rightaway (4.1 code 8)
# 40 - for root, same as 0 (used by rcS to remount root)
