init.c problem

[Pavel Samek]

Hi!

I have the following problem.
Situation:
- etherboot loads kernel
- kernel has IP auto configuration enabled (ip=dhcp),
   no initrd
- rootfs is on nfs, succesfuly mounted
- now busybox's init should start, but it writes:

init: can't open /dev/null: no such file or directory

- start-udev is started from init script (but this is not called due to 
that error) so there cannot be /dev/null before

I have found that the busybox 1.6.1 was the last version where 
everything  went ok. Then after the following patch [1]

--- busybox-1.6.1/init/init.c	Sat Jun 30 16:06:46 2007
+++ busybox-1.6.1-init/init/init.c	Thu Jul  5 01:16:26 2007

+		bb_sanitize_stdio();
  	}

  	s = getenv("TERM");

the version 1.7.0 does not work for me.

If I apply the following patch to the latest version 1.9.1, it works again:
