generating the initramfs on another box but the support is all present
to build for the "running" machine. For the former, you can boot the guest

Requirements:
- add btrfsctl scan for btrfs multi-devices (raid)
- teach dmsquash live-root to use rootflags
- trigger udev with action=add
-- fixed add_drivers handling
+- fixed add_drivers handling
- add sr_mod
- use pigz instead of gzip, if available
- boot from LVM mirrors and snapshots
dracut-005
==========
-- dcb support to dracut's FCoE support
+- dcb support to dracut's FCoE support
- add readonly overlay support for dmsquash
- add keyboard kernel modules
- dracut.conf: added add_dracutmodules
- add s390 network support
- fixed dracut-gencmdline for root=UUID or LABEL
- do not destroy assembled raid arrays if mdadm.conf present
-- mount /dev/shm
+- mount /dev/shm
- let udevd not resolve group and user names
- moved network from udev to initqueue
- improved debug output: specifying "rdinitdebug" now logs
- strip kernel modules which have no x bit set
- redirect stdin, stdout, stderr all RW to /dev/console
so the user can use "less" to view /init.log and dmesg
-- add new device mapper udev rules and dmeventd
+- add new device mapper udev rules and dmeventd
- fixed dracut-gencmdline for root=UUID or LABEL
- do not destroy assembled raid arrays if mdadm.conf present
- mount /dev/shm
Supported cmdline formats:
fcoe=<networkdevice>:<dcb|nodcb>
fcoe=<macaddress>:<dcb|nodcb>
-
+
Note currently only nodcb is supported, the dcb option is reserved for
future use.
-
+
Note letters in the macaddress must be lowercase!
-
+
Examples:
fcoe=eth0:nodcb
fcoe=4A:3F:4C:04:F8:D7:nodcb
-- Syslog support for dracut
+- Syslog support for dracut
This module provides syslog functionality in the initrd.
This is especially interesting when complex configuration being
used to provide access to the device the rootfs resides on.
dracut-0.7
==========
- dracut: strip binaries in initramfs
-
+
--strip
strip binaries in the initramfs (default)
-
+
--nostrip
do not strip binaries in the initramfs
- dracut-catimages
-
+
Usage: ./dracut-catimages [OPTION]... <initramfs> <base image>
[<image>...]
Creates initial ramdisk image by concatenating several images from the
command
line and /boot/dracut/
-
+
-f, --force Overwrite existing initramfs file.
-i, --imagedir Directory with additional images to add
(default: /boot/dracut/)
dracut-0.6
==========
- dracut: add --kernel-only and --no-kernel arguments
-
+
--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:
-
+

initrd-config.img

- dracut: add --kmoddir directory, where to look for kernel modules
-
+
-k, --kmoddir [DIR]
specify the directory, where to look for kernel modules
- firmware loading support
- new internal queue (initqueue)
initqueue now loops until /dev/root exists or root is mounted
-
+
init now has the following points to inject scripts:
-
+
/cmdline/*.sh
scripts for command line parsing
-
+
/pre-udev/*.sh
scripts to run before udev is started
-

/pre-trigger/*.sh
scripts to run before the main udev trigger is pulled
-
+
/initqueue/*.sh
runs in parallel to the udev trigger
Udev events can add scripts here with /sbin/initqueue.

a timeout.
Scripts can remove themselves from the initqueue by "rm $job".
-
+
/pre-mount/*.sh
scripts to run before the root filesystem is mounted
NFS is an exception, because it has no device node to be created
and mounts in the udev events
-
+
/mount/*.sh
scripts to mount the root filesystem
NFS is an exception, because it has no device node to be created
If the udev queue is empty and no root device is found or no root
filesystem was mounted, the user will be dropped to a shell after
a timeout.
-
+
/pre-pivot/*.sh
scripts to run before the real init is executed and the initramfs
disappears
All processes started before should be killed here.
-
+
The behaviour of the dmraid module demonstrates how to use the new
mechanism. If it detects a device which is part of a raidmember from a
udev rule, it installs a job to scan for dmraid devices, if the udev

Some general rules for writing modules:

switching to a new root. You can pass 'rdbreak=hookpoint', and the initramfs
