* Messages for package sys-fs/udev-200:
* CONFIG_DEVTMPFS: is not set when it should be.
* Please check to make sure these options are set correctly.
* Failure to do so may cause unexpected problems.
You have to check the following option in your kernel config :
Device Drivers-> Generic Driver
* Maintain a devtmpfs filesystem to mount at /dev.
For getting the devfs automatically mounted at boot time it makes sense to also enable the option
* Automount devtmpfs at /dev
