personally I consider Moblin an ordinary distro.

my biggest objection was to the use of boot time as argument.
That was and still is deceiving and false. There may be other arguments
for devfs, but I'm not going to get in the middle of those. But boot
time isn't it.

I do share frustration with Eric on how Kay and Greg have handled this.
It really felt like a combination of bullying, ignoring any contrarian
argument and just ramming stuff down. Not at all unlike the original
devfs fiasco. It has left me with a pretty bad taste in my mouth and
am pretty disappointed; I expected better.
