Hello world,

Array CD 3 is ready. This is the third in a series of milestone CD
images, released when they're known to be reasonably free of showstopper
CD-build or installer bugs, while representing very current snapshots of
Hoary. You can download it here:

See for access instructions. I
recommend rsync if possible, as you can then download future images
based on this one to save bandwidth.

Pre-release versions of Hoary are *not* encouraged for anyone needing a
stable system or anyone who is not comfortable running into occasional
breakage. They *are* recommended for Ubuntu developers and those who
want to help in testing, reporting, and fixing bugs.

Some notable installer improvements and bug-fixes in this release:

  * End-to-end secure netboot installation: all our Release files are
    signed using the archive signing key [1] or the CD image key [2],
    and the installer verifies these signatures at each step. (The
    netboot kernel and initrd themselves are contained in the CD images,
    which are accompanied by MD5SUMS and MD5SUMS.gpg files).

  * Timezone and username/password questions moved to the first stage.
    The question about installing packages from the network remains in
    the second stage for now, but will eventually be moved as well.

  * Rudimentary rescue mode added: boot with the 'rescue/enable=true'
    parameter to use it. Its UI still needs significant polishing work.

  * Default debconf priority dropped from critical to high, and several
    questions adjusted; this fixes some automatic installation
    scenarios, makes it easier to merge changes back and forward with
    Debian, and makes it possible to share code between the first and
    second stages.

  * Example sources.list lines for security/universe fixed.

  * Support for Smart Boot Manager should work better now, although I
    haven't tested it personally.

  * Size requirement for a USB drive used to boot the installer reduced
    to 8 megabytes.

  * Fixed installation on large filesystems with long device names

  * Much improved and more flexible kernel selection logic.

  * Fixed default hostname when network configuration is skipped in
    first stage (#2844).

  * Fix part of Array CD 2 erratum: the framebuffer should now reliably
    be loaded.

  * Several fixes to the ia64 installer; much work remains to be done.

Known installer issues:

  * On my amd64 system, grub enters an infinite loop trying to load
    stage 1.5. I've never seen this before, and suspect hardware
    problems, but if it affects other people too I'd like to know about
