With the /check infrastucture in place, dmraid is missing a check file.
Patch is built on top of Harald Hoyers merge tree
(git://git.surfsite.org/pub/git/dracut.git)
Shift some required functionality from switch_root.c to init.
String manipulation and filtering, and testing for the existence of init
is easier in the init script than in C.
The reason this works is that inst will refuse to overwrite a file that
already exists. We jsut make plymouth's code to ask for a password have the
same name as 90crypt's password asking script, and it will override 90crypt's
script while leaving everything else intact.
Followup: Harald Hoyers "Merge" repository boots on ub8.10 with a dracut.conf similar to the following one and the attached patch applied
> cat dracut.conf
modules="ata_piix sd_mod sg"
dracutmodules="dash kernel-modules debug terminfo udev-rules.ub810 base"
The switch_root shell script did not work with bash-4.0-2, because
"exec" gets the real path of the executable which is then
"/sysroot/lib/ld-linux.so.2" instread of "./lib/ld-linux.so.2".
Also the required chroot binary might live in /usr/bin, which can
be mounted later.
Here is the switch_root code from nash, which can be stripped down
further, but which works.

Subject: [PATCH] replace switch_root shell script with binary
The switch_root shell script did not work with bash-4.0-2, because
"exec" gets the real path of the executable which is then
"/sysroot/lib/ld-linux.so.2" instead of "./lib/ld-linux.so.2".
Also the required chroot binary might live in /usr/bin, which can
be mounted later.
Here is the switch_root code from nash, which can be stripped down
further, but which works.
They are not needed to boot with dracut, so away they go.
Also rewrite inst_rules to automatically search likely rule locations when
installing udev rules.
All modules now live in a subdirectory /modules.d. Each module is
self-contained -- it should contain everything that it will install
on the initrd. All modules must include a script named install, which
will be sourced by dracut. This script should do the actual file installation
using inst methods. The moddir variable will point to the full path to the
module dracut is currently working on.
As usual, this patch series applies on top of my previous patch series,
and is available as normalize-modules from http://git.fnordovax.org/dracut.
