  during loading

dmsquash-live:
- fixed livenet-generator execution flag
  and include only, if systemd is used
- fixed dmsquash-live-root.sh for cases where the fstype of the liveimage is squashfs
- fixed typo for rootfs.img
- enable the use of the OverlayFS for the LiveOS root filesystem
  Patch notes:
    Integrate the option to use an OverlayFS as the root filesystem
    into the 90dmsquash-live module for testing purposes.

    The rd.live.overlay.overlayfs option allows one to request an
    OverlayFS overlay.  If a persistent overlay is detected at the
    standard LiveOS path, the overlay & type detected will be used.

    Tested primarily with transient, in-RAM overlay boots on vfat-
    formatted Live USB devices, with persistent overlay directories
    on ext4-formatted Live USB devices, and with embedded, persistent
    overlay directories on vfat-formatted devices. (Persistent overlay
    directories on a vfat-formatted device must be in an embedded
    filesystem that supports the creation of trusted.* extended
    attributes, and must provide valid d_type in readdir responses.)

    The rd.live.overlay.readonly option, which allows a persistent
    overlayfs to be mounted read only through a higher level transient
    overlay directory, has been implemented through the multiple lower
    layers feature of OverlayFS.

    The default transient DM overlay size has been adjusted up to 32 GiB.
    This change supports comparison of transient Device-mapper vs.
    transient OverlayFS overlay performance.  A transient DM overlay
    is a sparse file in memory, so this setting does not consume more
    RAM for legacy applications.  It does permit a user to use all of
    the available root filesystem storage, and fails gently when it is
    consumed, as the available free root filesystem storage on a typical
    LiveOS build is only a few GiB.  Thus, when booted on other-
    than-small RAM systems, the transient DM overlay should not overflow.

    OverlayFS offers the potential to use all of the available free RAM
    or all of the available free disc storage (on non-vfat-devices)
    in its overlay, even beyond the root filesystem available space,
    because the OverlayFS root filesystem is a union of directories on
    two different partitions.

    This patch also cleans up some message spew at shutdown, shortens
    the execution path in a couple of places, and uses persistent
    DM targets where required.

iSCSI:
- use the iBFT initiator name, if found and set
- iscsid now present in the initramfs
- iscsistart is done with systemd-run asynchrone to do things in
  paralllel. Also restarted for every new interface which shows up.
- If rd.iscsi.waitnet (default) is set, iscsistart is done only
  after all interfaces are up.
- If not all interfaces are up and rd.iscsi.testroute (default) is set,
  the route to a iscsi target IP is checked and skipped, if there is none.
- If all things fail, we issue a "dummy" interface iscsiroot to retry
  everything in the initqueue/timeout.

- add options to tweak timeouts
     rd.net.dhcp.retry=<cnt>
         If this option is set, dracut will try to connect via dhcp
         <cnt> times before failing. Default is 1.

     rd.net.timeout.dhcp=<arg>
         If this option is set, dhclient is called with "-timeout <arg>".

dracut-043
==========
- add missing dmsquash-generator

dracut-042
==========
- fixed dmsetup shutdown
- new kernel command line option "rd.live.overlay.thin"
    This option changes the underlying mechanism for the overlay in the
    dmsquash module.
    Instead of a plain dm snapshot a dm thin snapshot is used. The advantage
    of the thin snapshot is, that the TRIM command is recognized, which
    means that at runtime, only the occupied blocks will be claimed from
    memory, and freed blocks will really be freed in ram.
- dmsquash: Add squashfs support to rd.live.fsimg
    Previously rd.live.fsimg only supported filesystems residing in
    (compressed) archives.
    Now rd.live.fsimg can also be used when a squashfs image is used.
    This is achieved by extracting the rootfs image from the squashfs and
    then continue with the default routines for rd.live.fsimg.
- lvm: add support for LVM system id
- split up the systemd dracut module
    Basic systemd functionality is in 00systemd now.
    Switching root and the initrd.target is in 00systemd-initrd.
    Dracut additions to the systemd initrd are in 98dracut-systemd.
- support for creating a UEFI boot executable via argument "--uefi"
    With an EFI stub, the kernel, the initramfs and a kernel cmdline can be
    glued together to a single UEFI executable, which can be booted by a
    UEFI BIOS.
- network: split out kernel-network-modules, now in 90kernel-network-modules
- support for ethernet point-to-point connections configured via DHCP
- kernel-modules: install all HID drivers
- dracut.pc pkg-config file
- mount /dev, /dev/shm and /run noexec

  if you want to boot on the same hardware, but the compiled in configuration
  does not match your setup anymore
- inst* functions and dracut-install now accept the "-H" flag, which logs all
  installed files to /lib/dracut/hostonly-files. This is used to remove those

  /usr/lib/dracut/dracut.conf.d/*.conf can be overwritten by the same
  filenames in /etc/dracut.conf.d.

  Packages should use /usr/lib/dracut/dracut.conf.d rather than
  /etc/dracut.conf.d for drop-in configuration files.

  /etc/dracut.conf and /etc/dracut.conf.d belong to the system administrator.

- uses systemd-198 native initrd units
- totally rely on the fstab-generator in systemd mode for block devices
- dracut systemd now uses dracut.target rather than basic.target
- dracut systemd services optimize themselves away
- fixed hostonly parameter generation
- turn off curl globbing (fixes IPv6)
- modify the udev rules on install and not runtime time
- enable initramfs building without kernel modules (fixed regression)
- in the initqueue/timeout,
  reset the main loop counter, as we see new udev events or initqueue/work
- fixed udev rule installation

dracut-021
==========

- 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

                  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.

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.
