dracut bug fix and enhancement update

Bug Fix Advisory

Topic

Updated dracut packages that fix multiple bugs and add two enhancements are now
available for Red Hat Enterprise Linux 6.

Description

The dracut packages include an event-driven initramfs generator infrastructure
based on udev. The virtual file system, initramfs, is loaded together with the
kernel at boot time and initializes the system, so it can read and boot from the
root partition.

This update fixes the following bugs:

• Previously, if a dracut module did not contain an "install" file, dracut could
  not execute the "installkernel" command. Consequently, the dracut fips-aesni
  module could not be included in the initramfs image. Now, "installkernel" can be
  correctly executed in the described scenario, thus fixing this bug. (BZ#788119)
  
• Previously, dracut failed to start up a degraded RAID array, resulting in a
  non-booting system. With this update, dracut uses the rd_retry kernel
  command-line parameter value and after rd_retry/2 seconds attempts to force the
  array to start, thus fixing this bug. (BZ#761584)
  
• During boot-up, dracut called the "udevadm settle" command several times. As a
  result, inconsequential messages about the command timeout were sometimes
  returned, creating clutter in the console output. This update fixes the bug and
  the messages are no longer returned in the described scenario. (BZ#747840)
  
• Occasionally, dracut attempted to assemble an array before all disks were
  available. As a result, dracut started the array in degraded mode or failed
  altogether. This bug has been fixed and dracut now forces degraded arrays to
  start only after a period of time controlled by the rd_retry kernel command-line
  parameter. (BZ#735529)
  
• The dracut package depended on the vconfig package although vconfig is not
  used by dracut. This update removes the dependency on vconfig. (BZ#714039)
  
• Previously, if a network interface was brought up, dracut waited for two
  seconds to detect that the link was up. For certain network cards, two seconds
  is not long enough. Consequently, the network was not properly set up and the
  system could not boot. Now, dracut waits for ten seconds, thus fixing this bug.
  (BZ#794863)
  
• Dracut did not set the broadcast address for network interfaces it started up,
  resulting in a 0.0.0.0 broadcast address. This bug has been fixed and the
  default broadcast address is now set properly on startup. (BZ#752584)
  
• The FILES section of the dracut man page has been amended to fix inaccurate
  content. (BZ#703164)
  
• If the user adds multiple "console=[tty]" parameters on the kernel command
  line, the last parameter specifies the primary console. Previously, dracut
  failed to initialize this console and instead initialized /dev/tty0
  unconditionally. This bug has been fixed and dracut now initializes the correct
  console in the described scenario. (BZ#752073)
  
• When no user name and password were specified in an iSCSI interface, dracut
  reused the login information from a previous iSCSI parameter. Consequently, the
  authentication failed and the system did not boot up. This update fixes the bug.
  (BZ#788618)
  

This update adds the following enhancements:

• Previously, it was not possible to exclude a kernel driver from the initramfs
  image to reduce its size. This update introduces the "--omit-driver" option to
  provide this functionality. (BZ#722879)
  
• The "lsinitrd" command has been enhanced to support initramfs images
  compressed by the LZMA algorithm. (BZ#752005)
  

Users of dracut are advised to upgrade to these updated packages, which fix
these bugs and add these enhancements.

Solution
