dracut-002
==========
- add ifname= argument for persistent netdev names

- fix for missing grep for md
dracut-001
==========
- better --hostonly checks
- better lvm/mdraid/dmraid handling
- fcoe booting support
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
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-0.9
==========
- let plymouth attach to the terminal (nice text output now)
- new kernel command line parameter "rdinfo" show dracut output, even when
"quiet" is specified
- rd_LUKS_UUID is now handled correctly
- dracut-gencmdline: rd_LUKS_UUID and rd_MD_UUID is now correctly generated
- now generates initrd-generic with around 15MB
- smaller bugfixes
dracut-0.8
==========
- iSCSI with username and password
- support for live images (dmsquashed live images)
- iscsi_firmware fixes
- smaller images
- bugfixes
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/)
-o, --overlaydir Overlay directory, which contains files that
will be used to create an additional image
--nooverlay Do not use the overlay directory
--noimagedir Do not use the additional image directory
-h, --help This message
--debug Output debug information of the build process
-v, --verbose Verbose output during the build process
- s390 dasd support
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:
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-kernel-2.6.29.5-191.fc11.i586.img /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
- dracut: add --kmoddir directory, where to look for kernel modules
-k, --kmoddir [DIR]
specify the directory, where to look for kernel modules
dracut-0.5
==========
- more generic (all plymouth modules, all keyboards, all console fonts)
- more kernel command line parameters (see also man dracut(8))
- a helper tool, which generates the kernel command line (dracut-gencmdline)
- bridged network boot
- a lot of new command line parameter
dracut-0.4
==========
- bugfixes
- 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.
If /sbin/initqueue is called with the "--onetime" option, the script
will be removed after it was run.
If /initqueue/work is created and udev >= 143 then this loop can
process the jobs in parallel to the udevtrigger.
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.
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
and mounts in the udev events
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
queue is empty. After a scan, it removes itsself from the queue.
dracut-0.3
