Hmmm... your udev based resume and root mounting do not work at all for
me. If I do not install the shell-based mount hooks, the root
filesystem never gets mounted -- I have to mount it manually.
Also,
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.
Followup: Harald Hoyers "Merge" repository boots on ub8.10 with a dracut.conf similar to the following one and the attached patch applied

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

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.
