udev now requires CONFIG_DEVTMPFS so make it default to y.
I noticed this when booting a ppc64 pseries_defconfig on Fedora 17
and it paniced because it couldn't mount the root device.

NAK. As Linus keeps saying we shouldn't go randomly turning features on
at people.
See the discussion on having a distro configuration - that will fix this
problem properly and for good.
You need half a dozen other things enabled to make Fedora boot many of
them quite obscure LVM settings.

All the world isn't Fedora :)
See Linus's recent thread about distro configs, that's the best solution
for something like this.
