Moblin appears to be the fastest boot and doesn't use it. I fact Arjan

"All". Thats a bit of a fiction.


But this is the wrong argument anyway

The question is
- Is it technically correct
- Does it properly interact with the rest of the kernel and upcoming stuff

So I'd like to see the fs folks sign off on it - which they've noticably
not done yet.

Whether you want devfs2 (ie devtmpfs) or static dev or udev is a
configuration and user dependant question no different to what fs do you
prefer. Whether it actually works and doesn't screw stuff up is a rather
more important technical question that needs proper review from the fs
list, which is notably lacking right now, except in the negative.
