rootfs is on nbd
In not hostonly mode, require_binaries will still complain.
If in hostonly mode and the module is explicitly added via -a nbd, then
install() section will still complain later:
dracut-install: ERROR: installing 'nbd-client'

Add new functions require_binaries() and require_any_binary() to be used
in the check() section of module-setup.sh.
These functions print a warning line telling the user, which binary is
missing for the specific dracut module.
This unifies the way of checking for binaries and makes the life of an
initramfs creator easier, if he wants to find out why a specific dracut
module is not included in the initramfs.
Previously if "$rootok" = 1, parsing of netroot command line arguments
was skipped. For multiple netroot arguments, all parse scripts have to
run.
Previously only the first netroot argument was taken into account for
the parsing scripts. Now every netroot argument is processed.
The following change makes the check for the nbd port or named export
more robust.
I wasn't sure whether to include sed in the dracut_install() of
module-setup.sh since net already does that (and nbd depends on that).
Name based connects fail because of the quotes around the $nbdport.
For name based connects, the -N option also gets included. For
instance nbd-client 192.168.0.1 '-N ltsp' /dev/nbd0.
I believe the quotes are not necessary for actual port numbers.
--kernel-only
only install kernel drivers and firmware files
--no-kernel
do not install kernel drivers and firmware files
All kernel module related install commands moved from "install"
to "installkernel".
For "--kernel-only" all installkernel scripts of the specified
modules are used, regardless of any checks, so that all modules
which might be needed by any dracut generic image are in.
The basic idea is to create two images. One image with the kernel
modules and one without. So if the kernel changes, you only have
to replace one image.
Grub and the kernel can handle multiple images, so grub entry can
look like this:
title Fedora (2.6.29.5-191.fc11.i586)
root (hd0,0)
kernel /vmlinuz-2.6.29.5-191.fc11.i586 ro rhgb quiet
initrd /initrd-20090722.img
initrd /initrd-kernel-2.6.29.5-191.fc11.i586.img
initrd /initrd-config.img
initrd-20090722.img
the image provided by the initrd rpm
one old backup version is kept like with the kernel
initrd-kernel-2.6.29.5-191.fc11.i586.img
the image provided by the kernel rpm
initrd-config.img
optional image with local configuration files
Udev rules set a /dev/root symlink to the real root and add
a mount script to /mount/. This enables the proper use of pre-mount
scripts and prevents mount being killed by a udev timeout.
Jobs are no longer handled inside the udev events.
/sbin/initqueue is called with the commands to queue.
init will work on these jobs sequentially, so that we prevent jobs
from being killed by udev timeouts.
This serialization also prevents some problems introduced by
the udev event parallelization.
Talked with Debian nbdroot author and he agreed we shouldn't support their obsolete syntax in dracut.
Their root=/dev/nbd[0-9] is no longer needed. Also their syntax was very standardized requiring
a separate boot= parameter.
