The boot options are prefixed by"devfs=", and are separated by commas. Spaces are not allowed. Thesyntax looks like this: devfs=<option1>,<option2>,<option3> and so on. For example, if you wanted to turn on debugging for moduleload requests and device registration, you would do: devfs=dmod,dreg You may prefix "no" to any option. This will invert the option.  Debugging Options================= These requires CONFIG_DEVFS_DEBUG to be enabled.Note that all debugging options have 'd' as the first character. Bydefault all options are off. All debugging output is sent to thekernel logs. The debugging options do not take effect until the devfsversion message appears (just prior to the root filesystem beingmounted). These are the options: dmod		print module load requests to <request_module> dreg		print device register requests to <devfs_register> dunreg		print device unregister requests to <devfs_unregister> dchange		print device change requests to <devfs_set_flags> dilookup	print inode lookup requests diget		print VFS inode allocations diunlink	print inode unlinks dichange	print inode changes dimknod		print calls to mknod(2) dall		some debugging turned on  Other Options============= These control the default behaviour of devfs. The options are: mount		mount devfs onto /dev at boot time only		disable non-devfs device nodes for devfs-capable drivers
