348 Usage: ./dracut-catimages [OPTION]... <initramfs> <base image>
350 Creates initial ramdisk image by concatenating several images from the
352 line and /boot/dracut/
354 -f, --force Overwrite existing initramfs file.
355 -i, --imagedir Directory with additional images to add
356 (default: /boot/dracut/)
357 -o, --overlaydir Overlay directory, which contains files that
358 will be used to create an additional image
359 --nooverlay Do not use the overlay directory
360 --noimagedir Do not use the additional image directory
361 -h, --help This message
362 --debug Output debug information of the build process
363 -v, --verbose Verbose output during the build process
369 - dracut: add --kernel-only and --no-kernel arguments
372 only install kernel drivers and firmware files
375 do not install kernel drivers and firmware files
377 All kernel module related install commands moved from "install"
380 For "--kernel-only" all installkernel scripts of the specified
381 modules are used, regardless of any checks, so that all modules
382 which might be needed by any dracut generic image are in.
384 The basic idea is to create two images. One image with the kernel
385 modules and one without. So if the kernel changes, you only have
386 to replace one image.
388 Grub and the kernel can handle multiple images, so grub entry can
391 title Fedora (2.6.29.5-191.fc11.i586)
393 kernel /vmlinuz-2.6.29.5-191.fc11.i586 ro rhgb quiet
394 initrd /initrd-20090722.img /initrd-kernel-2.6.29.5-191.fc11.i586.img /initrd-config.img
397 the image provided by the initrd rpm
398 one old backup version is kept like with the kernel
400 initrd-kernel-2.6.29.5-191.fc11.i586.img
401 the image provided by the kernel rpm
404 optional image with local configuration files
406 - dracut: add --kmoddir directory, where to look for kernel modules
409 specify the directory, where to look for kernel modules
415 - more generic (all plymouth modules, all keyboards, all console fonts)
416 - more kernel command line parameters (see also man dracut(8))
417 - a helper tool, which generates the kernel command line (dracut-gencmdline)
418 - bridged network boot
419 - a lot of new command line parameter
424 - firmware loading support
425 - new internal queue (initqueue)
426 initqueue now loops until /dev/root exists or root is mounted
428 init now has the following points to inject scripts:
431 scripts for command line parsing
434 scripts to run before udev is started
437 scripts to run before the main udev trigger is pulled
440 runs in parallel to the udev trigger
441 Udev events can add scripts here with /sbin/initqueue.
442 If /sbin/initqueue is called with the "--onetime" option, the script
443 will be removed after it was run.
444 If /initqueue/work is created and udev >= 143 then this loop can
445 process the jobs in parallel to the udevtrigger.
446 If the udev queue is empty and no root device is found or no root
447 filesystem was mounted, the user will be dropped to a shell after
449 Scripts can remove themselves from the initqueue by "rm $job".
452 scripts to run before the root filesystem is mounted
453 NFS is an exception, because it has no device node to be created
454 and mounts in the udev events
457 scripts to mount the root filesystem
458 NFS is an exception, because it has no device node to be created
459 and mounts in the udev events
460 If the udev queue is empty and no root device is found or no root
461 filesystem was mounted, the user will be dropped to a shell after
465 scripts to run before the real init is executed and the initramfs
467 All processes started before should be killed here.
469 The behaviour of the dmraid module demonstrates how to use the new
470 mechanism. If it detects a device which is part of a raidmember from a
471 udev rule, it installs a job to scan for dmraid devices, if the udev
472 queue is empty. After a scan, it removes itsself from the queue.
479 - first public version
