[RFC PATCH] dracut-update-initramfs and debian control files

[Philippe Seewer <philippe.seewer-omB+W0Dpw2o@public.gmane.org>]

Hello all!

Before filing a WTP to get dracut inside debian unstable I'd like your
comments on my work if possible. The patch below contains all necessary
control files to build dracut debian packages. (Written and tested on
debian unstable.)

A few comments:
- I've split dracut into two parts: The dracut package for booting from block
  devices and dracut-net for netroot.
- I've deliberately left out all redhat specific modules, they do not make any
  sense on debian at all
- dracut-update-initramfs is a copy from initramfs-tools' update-initramfs,
  with just a few lines modified to run dracut instead of mkinitramfs. 
- Lintian complains about a few things but these are easily fixed and will be
  done before filing a WTP

Thanks all,
Philippe

+Depends: bash, coreutils, cpio, dash, diffutils, awk, grep, gzip, module-init-tools, udev, ${misc:Depends}
+Provides: linux-initramfs-tool
+Description: A new initramfs infrastructure
+ Unlike existing initramfs's, this is an attempt at having as little as
+ possible hard-coded into the initramfs as possible.  The initramfs has
+ (basically) one purpose in life -- getting the rootfs mounted so that
+ we can transition to the real rootfs.  This is all driven off of
+ device availability.  Therefore, instead of scripts hard-coded to do
+ various things, we depend on udev to create device nodes for us and
+ then when we have the rootfs's device node, we mount and carry on. 
+ Having the root on MD, LVM2, LUKS is supported as well as NFS, iSCSI,
+ NBD and FCOE with dracut-net.
