Debian-Installer errata

Errata for Bookworm Alpha 1

This is a list of known problems in the Bookworm Alpha 1 release of the Debian Installer. If you do not see your problem listed here, please send us an installation report describing the problem.

Theme used in the installer
There's no Bookworm artwork yet, and the installer is still using the Bullseye theme.
Firmwares required for some sound cards
There seems to be a number of sound cards that require loading a firmware to be able to emit sound. As of Bullseye, the installer is not able to load them early, which means that speech synthesis during installation is not possible with such cards. A possible workaround is to plug another sound card which does not need such firmware. See the umbrella bug report to keep track of our efforts.
Desktop installations may not work using CD#1 alone
Due to space constraints on the first CD, not all of the expected GNOME desktop packages fit on CD#1. For a successful installation, use extra package sources (e.g. a second CD or a network mirror) or use a DVD instead.
Status: It is unlikely more efforts can be made to fit more packages on CD#1.
LUKS2 is incompatible with GRUB's cryptodisk support
It was only lately discovered that GRUB has no support for LUKS2. This means that users who want to use GRUB_ENABLE_CRYPTODISK and avoid a separate, unencrypted /boot, won't be able to do so (#927165). This setup isn't supported in the installer anyway, but it would make sense to at least document this limitation more prominently, and to have at least the possibility to opt for LUKS1 during the installation process.
Status: Some ideas have been expressed on the bug; cryptsetup maintainers have written some specific documentation.
