[Xen-devel] changing sysctl on kernel cmdline?

[Nils Toedtmann <xen-devel@xxxxxxxxxxxxxxxxxx>]

Hello *,

i need to switch a sysctl _before_ /sbin/init.

My case: I try use the micro-distribution "LEAF Bering-uClibc" with
FC4's kernel-xenU (a weird combination of 2.6.12-rc5 and xen-unstable
from 2005-04-24 ...). But its /sbin/init segfaults when 2.6.12's new
feature "address space randomisation" is active. Unfortunatly, that
means i cannot boot far enough to do

  sysctl -w kernel.randomize_va_space=0

Any ideas (besides using older 2.6.11 or patching kernel/sysctl.c)? I'd
like to put something like "sysctl:kernel.randomize_va_space=0" on the
domU kernel's cmdline.

/nils.
