Hello all, sorry to keep bringing this up but still a no go with todays
latest CVS of busybox and tinylogin.

Here is some nitty gritty:
kernel 2.4.2-3 on a RH6.2 machine (patched up to req libs)

bb Config.h:
/* vi: set sw=4 ts=4: */

// NOTE: This file only defines features usefull under the Hurd,
// To compile for the Hurd raname this to Config.h prior to make

// This file defines the feature set to be compiled into busybox.
// When you turn things off here, they won't be compiled in at all.
//
//// This file is parsed by sed. You MUST use single line comments.

// Turn this on to use Erik's very cool devps and devmtab kernel drivers,
// thereby eliminating the need for the /proc filesystem and thereby saving
// lots and lots memory for more important things.  You can not use this and
// USE_PROCFS at the same time...  NOTE:  If you enable this feature, you
// _must_ have patched the kernel to include the devps patch that is included
// in the busybox/kernel-patches directory.  You will also need to create some
// device special files in /dev on your embedded system:
//        mknod /dev/mtab c 10 22
//        mknod /dev/ps c 10 21
// I emailed Linus and this patch will not be going into the stock kernel.

// break without this will tell you on compile)...
// You can't use this and BB_FEATURE_USE_DEVPS_PATCH

Boot disk goes till it asks for the Root disk, it'll read it, uncompress
it and stop at Freeing unused kernel memory: 192k freed.

I don't use and inittab, but am just trying to get a shell prompt (default
behavoir from bb to come up.  I am not using an ld.so.conf/cache file
(docs said just add a kernel and an editor to bb and tinlylogin and away
you go!).

Any ideas???
