# Status return code bits
# no bits set = no errors
# bit 0 set = minimum modules aren't loaded
# bit 1 set = requested feature module isn't loaded
# bit 2 set = /dev/ipmi0 (or /dev/imb if using that instead) doesn't exist
# bit 3 set = /dev/watchdog doesn't exist
# bit 4 set = lockfile doesn't exist
# bit 5 set = modules are loaded even when asked to be unloaded
