71 Note letters in the macaddress must be lowercase!
75 fcoe=4A:3F:4C:04:F8:D7:nodcb
77 - Syslog support for dracut
78 This module provides syslog functionality in the initrd.
79 This is especially interesting when complex configuration being
80 used to provide access to the device the rootfs resides on.

96 - support for live images (dmsquashed live images)
97 - iscsi_firmware fixes
103 - dracut: strip binaries in initramfs
106 strip binaries in the initramfs (default)
109 do not strip binaries in the initramfs
112 Usage: ./dracut-catimages [OPTION]... <initramfs> <base image>
114 Creates initial ramdisk image by concatenating several images from the
116 line and /boot/dracut/
118 -f, --force Overwrite existing initramfs file.
119 -i, --imagedir Directory with additional images to add
120 (default: /boot/dracut/)
121 -o, --overlaydir Overlay directory, which contains files that
122 will be used to create an additional image
123 --nooverlay Do not use the overlay directory
124 --noimagedir Do not use the additional image directory
125 -h, --help This message
126 --debug Output debug information of the build process
127 -v, --verbose Verbose output during the build process
133 - dracut: add --kernel-only and --no-kernel arguments
136 only install kernel drivers and firmware files
139 do not install kernel drivers and firmware files
141 All kernel module related install commands moved from "install"
144 For "--kernel-only" all installkernel scripts of the specified
145 modules are used, regardless of any checks, so that all modules
146 which might be needed by any dracut generic image are in.
148 The basic idea is to create two images. One image with the kernel
149 modules and one without. So if the kernel changes, you only have
150 to replace one image.
152 Grub and the kernel can handle multiple images, so grub entry can
155 title Fedora (2.6.29.5-191.fc11.i586)
157 kernel /vmlinuz-2.6.29.5-191.fc11.i586 ro rhgb quiet
158 initrd /initrd-20090722.img /initrd-kernel-2.6.29.5-191.fc11.i586.img /initrd-config.img
161 the image provided by the initrd rpm
162 one old backup version is kept like with the kernel
164 initrd-kernel-2.6.29.5-191.fc11.i586.img
165 the image provided by the kernel rpm
168 optional image with local configuration files
170 - dracut: add --kmoddir directory, where to look for kernel modules
173 specify the directory, where to look for kernel modules
179 - more generic (all plymouth modules, all keyboards, all console fonts)
180 - more kernel command line parameters (see also man dracut(8))
181 - a helper tool, which generates the kernel command line (dracut-gencmdline)
182 - bridged network boot
183 - a lot of new command line parameter
188 - firmware loading support
189 - new internal queue (initqueue)
190 initqueue now loops until /dev/root exists or root is mounted
192 init now has the following points to inject scripts:
195 scripts for command line parsing
198 scripts to run before udev is started
201 scripts to run before the main udev trigger is pulled
204 runs in parallel to the udev trigger
205 Udev events can add scripts here with /sbin/initqueue.
206 If /sbin/initqueue is called with the "--onetime" option, the script
207 will be removed after it was run.
208 If /initqueue/work is created and udev >= 143 then this loop can
209 process the jobs in parallel to the udevtrigger.
210 If the udev queue is empty and no root device is found or no root
211 filesystem was mounted, the user will be dropped to a shell after
213 Scripts can remove themselves from the initqueue by "rm $job".
216 scripts to run before the root filesystem is mounted
217 NFS is an exception, because it has no device node to be created
218 and mounts in the udev events
221 scripts to mount the root filesystem
222 NFS is an exception, because it has no device node to be created
223 and mounts in the udev events
224 If the udev queue is empty and no root device is found or no root
225 filesystem was mounted, the user will be dropped to a shell after
229 scripts to run before the real init is executed and the initramfs
231 All processes started before should be killed here.
233 The behaviour of the dmraid module demonstrates how to use the new
234 mechanism. If it detects a device which is part of a raidmember from a
235 udev rule, it installs a job to scan for dmraid devices, if the udev
236 queue is empty. After a scan, it removes itsself from the queue.
