Make plymouth play nice with current ctypt code, part 2.
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.

Add dracutmodules=auto functionality
To use this, your module needs to supply a check script which returns 0
if the module is applicable to this system, 1 otherwise.
If a module does not include a check script, it will be sourced. If no modules
have check scripts, then dracutmodules=auto behaves exactly like
dracutmodules=all

Remove a useless use of cat in instmods
We also need to decide whenter we are going to support modules.* files.
Not only are they Fedora-specific, but doing so makes =* arguments to instmods
have two different and incompatible meanings depending on whether that file
exists.

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" 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.

Steal rules we need from the latest udev package.
This should arguably be done by importing the udev git repo as a submodule,
but I am too lazy to figure out how to do that right now.
I suppose this could also be done by rewriting the 95udev-rules.sh module
for each distribution, but that is something best left to the distro
maintainers once we acheive some sort of widespread adoption. Until then,
stealing rules from upstream udev seems like the most portable solution.

Modify instmods to not rely on the existence of modules.* files
This patch series aims to make dracut more distro-independent. It includes
some of the functionality that Seewer Philippe posted to the list to make
dracut work on Ubuntu.
depmod does not create these files on all distros (Debian, specifically),
so modify instmods to use pathname components and find to do what we want.
As a bonus, this removes the special-case for =ata.

Make bash regexes behave
On some systems with newer or unpatched bash versions the whole right

Fix instmods recursing indefinitely

Create a self-contained structure for dracut modules
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.

Move running dhclient on DHCP interfaces into a pre-mount hook.
Static interfaces are still configured on the fly as we add them, but
discussions on the mailing list have suggested that we need to have finer
control over bringing up dhcp interfaces.
The default hook just runs all the requested dhclients in parallel and waits
for them to all return. If you need something more complicated than this, or
need to have more control over bringing interfaces up, you will probably need
to override some stuff in the 40network hook.

We now know how to configure the network interfaces.
Provided that you are configuring them via DHCP. RARP, BOOTP, and static
configuration are not written yet.
Also, adding nic drivers really bloats the initrd.
I am looking for feedback on these patches from people who actually implement
booting over the network. This patch series does not include support for that
yet -- you will not find nfsroot= handling, or booting to a fs supplied by
dhcp yet. I do want to make it as easy as possible to add support for booting
over the network, as well as making it easy for people to customize things to
meet their site requirements.
This patch series is also available as the network-configurability branch at
http://git.fnordovax.org/dracut. It may be rebased without warning to keep
it in sync with the rest of dracut.
