/proc/devices missing


Hello everyone,

I am booting RH over network (PXE) with custom initrd.img. I managed to get NFS working and switch root and do normal RH /sbin/init, but as RH boots it complains about /proc/devices missing:

/proc/devices: fopen failed: No such file or directory

The file is indeed missing, even though I'm doing "modprobe dm_mod" before. But still /proc/devices is not created. What am I doing wrong?

init script for that initrd.img:

Code:
#!/bin/bash

export LD_LIBRARY_PATH=/lib:/usr/lib:/usr/kerberos/lib

mount -t proc /proc /proc
setquiet

Shouldn't you create actual directory "proc/devices". I do not see the mkdir line. I am not familiar with this, so I am just asking.
