I just fixed the patch for the FAQ. It's much simpler
(and correct, I hope) now.

-------------

I tried with the patched init/main.c and:

inittab:
1:2345:respawn:/usr/bin/env LD_ASSUME_KERNEL=2.4.1 /sbin/getty 38400 tty1

(w/o the LD_ASSUME_KERNEL=2.4.1 the entry in
/etc/environment).

And it dies just after I log in, but I don't get a panic,
just another password prompt. So I guess it's bash
who is not taking the environment that /sbin/init
sets...

And that's why things work when I set
the variable in "/etc/environment"

(and also send a modified environment to
/sbin/init .... with LD_ASSUME_KERNEL=2.4.1.
You must do both, I said that setting
/etc/environment was enough in my previous
email and I was quite wrong. Sorry).

Regards.
