120 - dracut: strip binaries in initramfs
123 strip binaries in the initramfs (default)
126 do not strip binaries in the initramfs
129 Usage: ./dracut-catimages [OPTION]... <initramfs> <base image>
131 Creates initial ramdisk image by concatenating several images from the
133 line and /boot/dracut/
135 -f, --force Overwrite existing initramfs file.
136 -i, --imagedir Directory with additional images to add
137 (default: /boot/dracut/)
138 -o, --overlaydir Overlay directory, which contains files that
139 will be used to create an additional image
140 --nooverlay Do not use the overlay directory
141 --noimagedir Do not use the additional image directory
142 -h, --help This message
143 --debug Output debug information of the build process
144 -v, --verbose Verbose output during the build process
150 - dracut: add --kernel-only and --no-kernel arguments
153 only install kernel drivers and firmware files
156 do not install kernel drivers and firmware files
158 All kernel module related install commands moved from "install"
161 For "--kernel-only" all installkernel scripts of the specified
162 modules are used, regardless of any checks, so that all modules
163 which might be needed by any dracut generic image are in.
165 The basic idea is to create two images. One image with the kernel
166 modules and one without. So if the kernel changes, you only have
167 to replace one image.
169 Grub and the kernel can handle multiple images, so grub entry can
172 title Fedora (2.6.29.5-191.fc11.i586)
174 kernel /vmlinuz-2.6.29.5-191.fc11.i586 ro rhgb quiet
175 initrd /initrd-20090722.img /initrd-kernel-2.6.29.5-191.fc11.i586.img /initrd-config.img

182 the image provided by the kernel rpm
185 optional image with local configuration files
187 - dracut: add --kmoddir directory, where to look for kernel modules
190 specify the directory, where to look for kernel modules
196 - more generic (all plymouth modules, all keyboards, all console fonts)
197 - more kernel command line parameters (see also man dracut(8))
198 - a helper tool, which generates the kernel command line (dracut-gencmdline)
199 - bridged network boot
200 - a lot of new command line parameter
205 - firmware loading support
206 - new internal queue (initqueue)
207 initqueue now loops until /dev/root exists or root is mounted
209 init now has the following points to inject scripts:
212 scripts for command line parsing
215 scripts to run before udev is started
218 scripts to run before the main udev trigger is pulled
221 runs in parallel to the udev trigger
222 Udev events can add scripts here with /sbin/initqueue.
223 If /sbin/initqueue is called with the "--onetime" option, the script
224 will be removed after it was run.
225 If /initqueue/work is created and udev >= 143 then this loop can
226 process the jobs in parallel to the udevtrigger.
227 If the udev queue is empty and no root device is found or no root
228 filesystem was mounted, the user will be dropped to a shell after
230 Scripts can remove themselves from the initqueue by "rm $job".
233 scripts to run before the root filesystem is mounted
234 NFS is an exception, because it has no device node to be created
235 and mounts in the udev events
238 scripts to mount the root filesystem
239 NFS is an exception, because it has no device node to be created
240 and mounts in the udev events
241 If the udev queue is empty and no root device is found or no root
242 filesystem was mounted, the user will be dropped to a shell after
246 scripts to run before the real init is executed and the initramfs
248 All processes started before should be killed here.
250 The behaviour of the dmraid module demonstrates how to use the new
251 mechanism. If it detects a device which is part of a raidmember from a
252 udev rule, it installs a job to scan for dmraid devices, if the udev
253 queue is empty. After a scan, it removes itsself from the queue.
