Debian Installer Buster RC 1 release

The Debian Installer team[1] is pleased to announce the first release
candidate of the installer for Debian 10 "Buster".

Important change in this release

This release includes Secure Boot support on amd64, which should work
out of the box on most Secure Boot enabled machines. This means there
should be no need to disable Secure Boot support in the firmware
configuration anymore.

Improvements in this release

 * apt-setup:
    - Adjust handling of media sets, improving support for Debian Edu.
 * brltty:
    - Add support for Hedo MobiLine.
 * cdebconf:
    - Disable paging in text frontend for now, espeakup does not
      pronounce the keys to change pages (see #690343) and thus users
      are confounded and think the first page are the only choices.
 * cryptsetup:
    - The on-disk LUKS format version now defaults to LUKS2 (#919725).
 * debian-installer:
    - Switch to using buster artwork for the splash screen.
    - Bump Linux kernel ABI from 4.19.0-1 to 4.19.0-4.
    - Improve build reproducibility (#900918, #920631, #920676).
    - gen-tarball: stop using the deprecated GZIP variable.
    - gen-tarball: use pigz automatically if it is available.
    - Add dark theme submenu and shortcut: 'd' (#820911).
    - Fix loading background image on netboot grub.
 * debian-installer-utils:
    - Stop propagating BOOTIF to the installed system (#921444).
 * espeakup:
    - Fix writing down sound card ID when the installation finishes.
 * finish-install:
    - Add support for multiple consoles.
 * grub-installer:
    - On Linux, mount/unmount /run to work around timeouts during LVM
      initialization (#918590).
 * grub2:
    - Fix setup on Secure Boot systems where cryptodisk is in use
    - Make grub-efi-amd64-signed recommend shim-signed (#919067).
    - Add help and ls modules to signed UEFI images (#919955).
    - grub-install: Check for arm-efi as a default target (#922104).
    - util: Detect more I/O errors, like insufficient space (#922741).
    - Use libefi* libraries to minimise writes to EFI variable storage
      (#891434), instead of depending on efibootmgr. (The latter is
      expected to come back in Recommends in a later release, since
      that's a useful debugging tool.)
 * hw-detect:
    - Use 'modprobe -qn' to query available modules (#870448).
 * libxinerama:
    - Fix udeb dependencies (#921715).
 * linux:
    - certs: Replace test signing certificate with production signing
    - certs: include both root CA and direct signing certificate
 * live-installer:
    - Add calamares-settings-debian as package to be removed at the
      end of the installation.
 * nano:
    - Add patch to avoid showing ^S and ^Q options in nano-tiny, as
      using those can cause problems on some d-i environments, like
      installs over serial console (#915017).
 * network-console:
    - Drop “beep” support for arm*/ixp4xx and arm*/iop32x; it was used
      to notify users their devices was ready to be installed, but
      support for those platforms was removed from the Linux kernel
      and therefore d-i (#921951).
 * partman-base:
    - Make sure UUIDs are available in /dev/disk/by-uuid/ so that the
      bootloader can be configured to use them (#852323).
 * partman-lvm:
    - Really fix invalid characters in volume group names (#911036),
      the the previous attempt was not entirely functional (#922230,
 * partman-partitioning:
    - Use GPT by default on armhf/efi, MSDOS otherwise.
 * rootskel:
    - Make theme=dark install and enable Compiz in MATE.
    - Make theme=dark make grub use a dark theme.
    - Run d-i on multiple consoles independently where configured.
    - Add error-handling to steal-ctty.
    - Add early logging so we can later see what consoles are detected
      and chosen.
 * rootskel-gtk:
    - Integrate Buster theme: futureprototype.
 * systemd:
    - udev: Run programs in the specified order (#925190).
    - udev: Prevent mass killings when not running under systemd

    - Make all arm32 machines with EFI show up as subarch efi.
 * linux:

Localization status

 * 76 languages are supported in this release.
 * Full translation for 38 of them.

Known bugs in this release

 * TLS support in wget is broken (#926315).
 * Even if there weren't issues in the openssl udebs, one might run
   into issues related to missing entropy (#923675). This affects
   HTTPS connections, but also SSH keypair generation.
 * The switch to LUKS2 means one cannot use GRUB's cryptodisk support

See the errata[2] for details and a full list of known issues.
