I'm running a diskless machine with DEVFS and DEVFS_ROOT, it has an
IDE disk.
I mount DEVFS early in /sbin/init:
(Warning cut&pasted, \t's are lost)

The following script hangs if devfs is mounted on /dev, but not if
it is mounted on /devfs:
:
fsck -y /dev/rwd0s*[ae]
mount /dev/wd0s4e /mnt
cd /usr
find X* -print | cpio -dumpV /mnt
The machine as such is OK, but cpio is hung:
0 169 1 16 -5 0 212 496 getblk D p0- 0:00.55 cpio -dumpV
And gradually other processes take permanent leave in getblk too.
There are a couple of other patches needed, but they are not important
I think, anyway, I will commit them now, so people can try this out.
