Bug#557439: devtmpfs

[Joey Korkames <joey@kidfixit.com>]

I think running "mount -t devtmpfs devtmpfs /dev" early on in 
/usr/share/initramfs-tools/init would fix this problem. 

Here's an example boot script:

devtmpfs is a new filesystem in the 2.6.32+ kernels, so it would be only 
do-able with sid's linux-image-* packages for now.
