[thirdparty/dracut.git] / NEWS

dracut-023
==========
- resume from hibernate fixes
- -N option for --no-hostonly
- support for systemd crypto handling
- new dracut module "crypt-loop"
- deprecate the old kernel command line options
- more documentation
- honor CFLAGS for dracut-install build
- multipath fixes
- / is mounted according to rootflags parameter but forced ro at first.
  Later it is remounted according to /etc/fstab + rootflags parameter
  and "ro"/"rw".
- support for xfs / reiserfs separate journal device
- new "ro_mnt" option to force ro mount of / and /usr
- root on cifs support
- dracut-install: fixed issue for /var/tmp containing a symlink
- only lazy resolve with ldd, if the /var/tmp partition is not mounted with "noexec"
- i18n: fixed inclusion of "include" keymaps

dracut-022
==========
- fixed host-only kernel module bug

dracut-021
==========
- fixed systemd in the initramfs (requires systemd >= 187)
- dracut-install: massive speedup with /var on the same filesystem with COW copy
- dracut-install: moved to /usr/lib/dracut until it becomes a general purpose tool
- new options: "rd.usrmount.ro" and "rd.skipfsck"
- less mount/umount
- apply "ro" on the kernel command line also to /usr
- mount according to fstab, if neither "ro" or "rw" is specified
- skip fsck for xfs and btrfs. remount is enough
- give emergency_shell if /usr mount failed
- dracut now uses getopt:
  * options can be position independent now!!
  * we can now use --option=<arg>
- added option "--kver=<kernel-version>", and the image location can be omitted
  # dracut --kver 3.5.0-0.rc7.git1.2.fc18.x86_64
- dracut.sh: for --include copy also the symbolic links
- man pages: lsinitrd and mkinitrd added
- network: We do not support renaming in the kernel namespace anymore (as udev does
  that not anymore). So, if a user wants to use ifname, he has to rename
  to a custom namespace. "eth[0-9]+" is not allowed anymore. !!!!!
- resume: moved the resume process to the initqueue.
  This should prevent accidently mounting the root file system.
- testsuite: add support for: make V=1 TESTS="01 20 40" check
    $ sudo make V=1 clean check
    now runs the testsuite in verbose mode

    $ sudo make TESTS="01 20 40" clean check
    now only runs the 01, 20 and 40 tests.

                  do not strip binaries in the initramfs
- dracut-catimages

    Usage: ./dracut-catimages [OPTION]... <initramfs> <base image>

    line and /boot/dracut/

      -f, --force           Overwrite existing initramfs file.
      -i, --imagedir        Directory with additional images to add
                            (default: /boot/dracut/)

      -v, --verbose         Verbose output during the build process

- s390 dasd support

dracut-0.6
==========
- dracut: add --kernel-only and --no-kernel arguments

           --kernel-only
                  only install kernel drivers and firmware files

           --no-kernel
                  do not install kernel drivers and firmware files

    All kernel module related install commands moved from "install"
    to "installkernel".

    For "--kernel-only" all installkernel scripts of the specified
    modules are used, regardless of any checks, so that all modules
    which might be needed by any dracut generic image are in.

    The basic idea is to create two images. One image with the kernel
    modules and one without. So if the kernel changes, you only have
    to replace one image.

    Grub and the kernel can handle multiple images, so grub entry can
    look like this:

    title Fedora (2.6.29.5-191.fc11.i586)
            root (hd0,0)
            kernel /vmlinuz-2.6.29.5-191.fc11.i586 ro rhgb quiet
            initrd /initrd-20090722.img /initrd-kernel-2.6.29.5-191.fc11.i586.img /initrd-config.img

    initrd-20090722.img
      the image provided by the initrd rpm
      one old backup version is kept like with the kernel

    initrd-kernel-2.6.29.5-191.fc11.i586.img
      the image provided by the kernel rpm

    initrd-config.img
      optional image with local configuration files

- dracut: add --kmoddir directory, where to look for kernel modules

           -k, --kmoddir [DIR]
                  specify the directory, where to look for kernel modules



dracut-0.5
==========
- more generic (all plymouth modules, all keyboards, all console fonts)
- more kernel command line parameters (see also man dracut(8))
- a helper tool, which generates the kernel command line (dracut-gencmdline)
- bridged network boot
- a lot of new command line parameter

dracut-0.4
==========
- bugfixes
- firmware loading support
- new internal queue (initqueue)
    initqueue now loops until /dev/root exists or root is mounted

    init now has the following points to inject scripts:

    /cmdline/*.sh
       scripts for command line parsing

    /pre-udev/*.sh
       scripts to run before udev is started

    /pre-trigger/*.sh
       scripts to run before the main udev trigger is pulled

    /initqueue/*.sh
       runs in parallel to the udev trigger
       Udev events can add scripts here with /sbin/initqueue.
       If /sbin/initqueue is called with the "--onetime" option, the script
       will be removed after it was run.
       If /initqueue/work is created and udev >= 143 then this loop can
       process the jobs in parallel to the udevtrigger.
       If the udev queue is empty and no root device is found or no root
       filesystem was mounted, the user will be dropped to a shell after
       a timeout.
       Scripts can remove themselves from the initqueue by "rm $job".

    /pre-mount/*.sh
       scripts to run before the root filesystem is mounted
       NFS is an exception, because it has no device node to be created
       and mounts in the udev events

    /mount/*.sh
       scripts to mount the root filesystem
       NFS is an exception, because it has no device node to be created
       and mounts in the udev events
       If the udev queue is empty and no root device is found or no root
       filesystem was mounted, the user will be dropped to a shell after
       a timeout.

    /pre-pivot/*.sh
       scripts to run before the real init is executed and the initramfs
       disappears
       All processes started before should be killed here.

    The behaviour of the dmraid module demonstrates how to use the new
    mechanism. If it detects a device which is part of a raidmember from a
    udev rule, it installs a job to scan for dmraid devices, if the udev
    queue is empty. After a scan, it removes itsself from the queue.
