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

}
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:
