138 - Syslog support for dracut

164 - dracut: strip binaries in initramfs
167 strip binaries in the initramfs (default)
170 do not strip binaries in the initramfs
173 Usage: ./dracut-catimages [OPTION]... <initramfs> <base image>
175 Creates initial ramdisk image by concatenating several images from the
177 line and /boot/dracut/
179 -f, --force Overwrite existing initramfs file.
180 -i, --imagedir Directory with additional images to add
181 (default: /boot/dracut/)
182 -o, --overlaydir Overlay directory, which contains files that
183 will be used to create an additional image
184 --nooverlay Do not use the overlay directory
185 --noimagedir Do not use the additional image directory
186 -h, --help This message
187 --debug Output debug information of the build process
188 -v, --verbose Verbose output during the build process
194 - dracut: add --kernel-only and --no-kernel arguments
197 only install kernel drivers and firmware files
200 do not install kernel drivers and firmware files
202 All kernel module related install commands moved from "install"
205 For "--kernel-only" all installkernel scripts of the specified
206 modules are used, regardless of any checks, so that all modules
207 which might be needed by any dracut generic image are in.
209 The basic idea is to create two images. One image with the kernel
210 modules and one without. So if the kernel changes, you only have
211 to replace one image.
213 Grub and the kernel can handle multiple images, so grub entry can
216 title Fedora (2.6.29.5-191.fc11.i586)
218 kernel /vmlinuz-2.6.29.5-191.fc11.i586 ro rhgb quiet
219 initrd /initrd-20090722.img /initrd-kernel-2.6.29.5-191.fc11.i586.img /initrd-config.img
222 the image provided by the initrd rpm
223 one old backup version is kept like with the kernel
225 initrd-kernel-2.6.29.5-191.fc11.i586.img
226 the image provided by the kernel rpm
229 optional image with local configuration files
231 - dracut: add --kmoddir directory, where to look for kernel modules
234 specify the directory, where to look for kernel modules
240 - more generic (all plymouth modules, all keyboards, all console fonts)
241 - more kernel command line parameters (see also man dracut(8))
242 - a helper tool, which generates the kernel command line (dracut-gencmdline)
243 - bridged network boot
244 - a lot of new command line parameter
249 - firmware loading support
250 - new internal queue (initqueue)
251 initqueue now loops until /dev/root exists or root is mounted
253 init now has the following points to inject scripts:
256 scripts for command line parsing
259 scripts to run before udev is started
262 scripts to run before the main udev trigger is pulled
265 runs in parallel to the udev trigger
266 Udev events can add scripts here with /sbin/initqueue.
267 If /sbin/initqueue is called with the "--onetime" option, the script
268 will be removed after it was run.
269 If /initqueue/work is created and udev >= 143 then this loop can
270 process the jobs in parallel to the udevtrigger.
271 If the udev queue is empty and no root device is found or no root
272 filesystem was mounted, the user will be dropped to a shell after
274 Scripts can remove themselves from the initqueue by "rm $job".
277 scripts to run before the root filesystem is mounted
278 NFS is an exception, because it has no device node to be created
279 and mounts in the udev events
282 scripts to mount the root filesystem
283 NFS is an exception, because it has no device node to be created
284 and mounts in the udev events
285 If the udev queue is empty and no root device is found or no root
286 filesystem was mounted, the user will be dropped to a shell after
290 scripts to run before the real init is executed and the initramfs
292 All processes started before should be killed here.
294 The behaviour of the dmraid module demonstrates how to use the new
295 mechanism. If it detects a device which is part of a raidmember from a
296 udev rule, it installs a job to scan for dmraid devices, if the udev
297 queue is empty. After a scan, it removes itsself from the queue.
