---------------
casper (1.327) quantal; urgency=low

  [ Tim Lunn ]
  * add gnome-shell favorites tweak to 25adduser
  * Add 16gdmnopasswd script, removes gdm password dialog for live user.

  [ Stéphane Graber ]
  * Fix casper when running on some RAID systems. (LP: #1047316, LP: #965735)
  * Apply patch by Tyler Gates to try and better handle dm devices, should help
    with the above change too. (LP: #865529)
  * Use /sys/class/net/ instead of hardcoded eth* devices.
    (LP: #905828, LP: #962546)
  * Allow overriding username/userfullname/hostname on the boot command line
    as is mentioned in the manpage but was never implemented.
    Note that when using persistence, those used for the first boot will be
    remembered through /etc/casper.conf (LP: #907482)
  * Reset oem-config/enable to false every boot. (LP: #838680)
  * Add Breaks/Replaces to ubiquity-casper to properly upgrade when both
    casper and ubiquity-casper are installed. (LP: #1046300)
  * Apply patch by cleary to avoid hang in 41apt_cdrom when .disk/info doesn't
    exist. (LP: #909919)
  * Eject by block device instead of mountpoint, this should avoid ejecting
    the cdrom on USB installations. (LP: #869238)
  * Add 'check' target to debian/rules based on ubiquity's (LP: #570243)

Title:
  support for biosdevname in livecd's

Status in “casper” package in Ubuntu:
  Fix Released

Bug description:
  Enabling biosdevname (described at
  http://linux.dell.com/files/whitepapers/consistent_network_device_naming_in_linux.pdf)
  is an option for Ubuntu and has been since 11.04. It is not yet
  enabled by default, but it is an option that can be enabled by passing
  the "biosdevname=1" option at boot. I am not sure if it is desired to
  allow this feature in live images (such as the Ubuntu Cloud live
  image), but, if it is, it seems like there may be a couple of bugs one
  may encounter when doing so because of a couple files in the casper
  package:

  dell at dhcp-164-224:~/precise/casper-1.312$ egrep -r "eth" * | egrep -vi "([a-z]eth|eth[a-z]|^test|^doc|^po|^man)"
  debian/changelog:  * Write /etc/network/interfaces entries for eth0, eth1, eth2, ath0 and
  scripts/casper-bottom/23networking:        for interface in /sys/class/net/eth* /sys/class/net/ath* /sys/class/net/wlan*; do
  scripts/casper-bottom/23networking:    for i in eth0 eth1 eth2 ath0 wlan0; do
  scripts/casper-bottom/24preseed:        chroot /root dhclient eth0 3>&- 4<&-
  scripts/casper-bottom/24preseed:        chroot /root ifconfig eth0 down

  I am not familiar with how casper functions, so I'm not sure if this
  would be a bug or if these files in scripts/casper-bottom are
  harmless. I will note that on an Ubuntu Cloud live image that I tried,
  passing "biosdevname=1" did not do anything, so it may be that this is
  not possible for that build anyway.
