1 - fixed dracut-gencmdline for root=UUID or LABEL
2 - do not destroy assembled raid arrays if mdadm.conf present
4 - let udevd not resolve group and user names
5 - preserve timestamps of tools on initramfs generation
6 - generate symlinks for binaries correctly
7 - moved network from udev to initqueue
8 - mount nfs3 with nfsvers=3 option and retry with nfsvers=2
9 - fixed nbd initqueue-finished
10 - improved debug output: specifying "rdinitdebug" now logs
11 to dmesg, console and /init.log
12 - stop udev before killing it
13 - add ghost /var/log/dracut.log
14 - dmsquash: use info() and die() rather than echo
15 - strip kernel modules which have no x bit set
16 - redirect stdin, stdout, stderr all RW to /dev/console
17 so the user can use "less" to view /init.log and dmesg
18 - make install of new dm/lvm udev rules optionally
19 - correct dasd module typo
20 - add new device mapper udev rules and dmeventd
21 - Fix LiveCD boot regression

23 selinux=0 not specified on kernel command line
24 - set finished criteria for dmsquash live images
25 - do not cleanup dmraids
30 - add ifname= argument for persistent netdev names
31 - new /initqueue-finished to check if the main loop can be left
32 - copy mdadm.conf if --mdadmconf set or mdadmconf in dracut.conf
33 - plymouth: use plymouth-populate-initrd
34 - add add_drivers for dracut and dracut.conf
35 - add modprobe scsi_wait_scan to be sure everything was scanned
36 - fix for several problems with md raid containers
37 - fix for selinux policy loading
38 - fix for mdraid for IMSM
39 - fix for bug, which prevents installing 61-persistent-storage.rules (bug #520109)
40 - fix for missing grep for md
44 - better --hostonly checks
45 - better lvm/mdraid/dmraid handling
46 - fcoe booting support
47 Supported cmdline formats:
48 fcoe=<networkdevice>:<dcb|nodcb>
49 fcoe=<macaddress>:<dcb|nodcb>
51 Note currently only nodcb is supported, the dcb option is reserved for
54 Note letters in the macaddress must be lowercase!
58 fcoe=4A:3F:4C:04:F8:D7:nodcb
60 - Syslog support for dracut
61 This module provides syslog functionality in the initrd.
62 This is especially interesting when complex configuration being
63 used to provide access to the device the rootfs resides on.
68 - let plymouth attach to the terminal (nice text output now)
69 - new kernel command line parameter "rdinfo" show dracut output, even when
71 - rd_LUKS_UUID is now handled correctly
72 - dracut-gencmdline: rd_LUKS_UUID and rd_MD_UUID is now correctly generated
73 - now generates initrd-generic with around 15MB
78 - iSCSI with username and password
79 - support for live images (dmsquashed live images)
80 - iscsi_firmware fixes
86 - dracut: strip binaries in initramfs
89 strip binaries in the initramfs (default)
92 do not strip binaries in the initramfs
95 Usage: ./dracut-catimages [OPTION]... <initramfs> <base image>
97 Creates initial ramdisk image by concatenating several images from the
99 line and /boot/dracut/
101 -f, --force Overwrite existing initramfs file.
102 -i, --imagedir Directory with additional images to add
103 (default: /boot/dracut/)
104 -o, --overlaydir Overlay directory, which contains files that
105 will be used to create an additional image
106 --nooverlay Do not use the overlay directory
107 --noimagedir Do not use the additional image directory
108 -h, --help This message
109 --debug Output debug information of the build process
110 -v, --verbose Verbose output during the build process
116 - dracut: add --kernel-only and --no-kernel arguments
119 only install kernel drivers and firmware files
122 do not install kernel drivers and firmware files
124 All kernel module related install commands moved from "install"
127 For "--kernel-only" all installkernel scripts of the specified
128 modules are used, regardless of any checks, so that all modules
129 which might be needed by any dracut generic image are in.
131 The basic idea is to create two images. One image with the kernel
132 modules and one without. So if the kernel changes, you only have
133 to replace one image.
135 Grub and the kernel can handle multiple images, so grub entry can
138 title Fedora (2.6.29.5-191.fc11.i586)
140 kernel /vmlinuz-2.6.29.5-191.fc11.i586 ro rhgb quiet
141 initrd /initrd-20090722.img /initrd-kernel-2.6.29.5-191.fc11.i586.img /initrd-config.img
144 the image provided by the initrd rpm
145 one old backup version is kept like with the kernel
147 initrd-kernel-2.6.29.5-191.fc11.i586.img
148 the image provided by the kernel rpm
151 optional image with local configuration files
153 - dracut: add --kmoddir directory, where to look for kernel modules
156 specify the directory, where to look for kernel modules
162 - more generic (all plymouth modules, all keyboards, all console fonts)
163 - more kernel command line parameters (see also man dracut(8))
164 - a helper tool, which generates the kernel command line (dracut-gencmdline)
165 - bridged network boot
166 - a lot of new command line parameter
171 - firmware loading support
172 - new internal queue (initqueue)
173 initqueue now loops until /dev/root exists or root is mounted
175 init now has the following points to inject scripts:
178 scripts for command line parsing
181 scripts to run before udev is started
184 scripts to run before the main udev trigger is pulled
187 runs in parallel to the udev trigger
188 Udev events can add scripts here with /sbin/initqueue.
189 If /sbin/initqueue is called with the "--onetime" option, the script
190 will be removed after it was run.
191 If /initqueue/work is created and udev >= 143 then this loop can
192 process the jobs in parallel to the udevtrigger.
193 If the udev queue is empty and no root device is found or no root
194 filesystem was mounted, the user will be dropped to a shell after
196 Scripts can remove themselves from the initqueue by "rm $job".
199 scripts to run before the root filesystem is mounted
200 NFS is an exception, because it has no device node to be created
201 and mounts in the udev events
204 scripts to mount the root filesystem
205 NFS is an exception, because it has no device node to be created
206 and mounts in the udev events
207 If the udev queue is empty and no root device is found or no root
208 filesystem was mounted, the user will be dropped to a shell after
212 scripts to run before the real init is executed and the initramfs
214 All processes started before should be killed here.
216 The behaviour of the dmraid module demonstrates how to use the new
217 mechanism. If it detects a device which is part of a raidmember from a
218 udev rule, it installs a job to scan for dmraid devices, if the udev
219 queue is empty. After a scan, it removes itsself from the queue.
