Hi
in 2.6.32 devtmpfs a early devfs created by the kernel is available and added
to the kernel config by default
grep "DEVTMPFS" config-2.6.32
CONFIG_DEVTMPFS_MOUNT=y
CONFIG_DEVTMPFS=y
this means: devtmpfs is mounted on root by the kernel. but its not used ...
this patches moves devtmpfs if available to root instead of using devfs...
greets
