Debian Installer Trixie RC 1 release

May 17th, 2025

The Debian Installer team is pleased to announce the first release candidate of the installer for Debian 13 Trixie.

Foreword

Cyril would like to dedicate this release to his dad, Gérard Brûlebois, the nicest and kindest man one could ever dream of.

Improvements in this release

base-installer:
- Exclude *-signed-template packages from kernel selection (#1104907).
debian-cd:
- Improve source package management.
- Update Debian-edu-full task file (#1079261).
- Don't include large graphics firmware packages on armhf builds.
- Exclude some firmware packages, either globally or on a per-arch basis, e.g. if they're not expected to be useful within the installer, without non-free components, and/or with the current Linux kernel configuration options.
- Update the list of devices supported by the firmware-sof-signed firmware package, which fixes speech synthesis on some hardware.
debian-installer:
- [arm64] Increase SD card image sizes for netboot (150MB → 300MB) and netboot-gtk (200MB → 400MB).
- Bump Linux kernel ABI to 6.12.27.
- Drop support for win32-loader.
- Add initial support for the Ceratopsian theme (Debian 13).
debian-installer-utils:
- Recognize persistent memory block devices (#879106).
debootstrap:
- Do not pull in usr-is-merged in trixie/sid (#1091649).
espeakup:
- Fix input when the installer starts.
gnupg2:
- gpgv: Avoid dependencies on npth and libassuan (#1102621).
grub-installer:
- Fix wrong or empty bootdev value for grub-pc (#1035096, #1058638).
- When installing a grub-efi* package and when efibootmgr is available, use it to dump the bootloader configuration, for debugging purposes (#931917).
- Fix some grub-installer/os-prober quirks (#1035085):
  - Fix inverted supported/unsupported OS logic in expert mode.
  - Mark efi, macosx, and minix os-prober types as supported.
  - Don't enable os-prober when there's not a single supported OS.
  - Only ask about os-prober once.
- Remove grub-legacy support (#1086750, #1086840).
- Skip grub-installer on non-EFI armhf (#1091441).
haveged:
- Ensure /dev/shm's presence, otherwise the daemon exits early.
hw-detect:
- Install spice-vdagent under QEMU/KVM if we are installing a desktop, i.e. if xserver-xorg-core or task-desktop are installed (#986500).
- Ignore renesas_usb_fw.mem requested by xhci-pci-renesas when falling back to the ROM. Devices might already work at this point, and a reload would risk making them disappear all of a sudden. This can catastrophic if that affects the installation medium (#1105000). Hats off to Felix Crux for a stellar installation report!
- ethdetect: Show description for compressed kernel modules.
- ethdetect: Allow commas in the description of modules (#1090738).
netcfg:
- Reject invalid input for static nameserver configuration.
- Update netcfg/get_netmask with masklen on static IP address.
partman-auto:
- ppc64el: revert /boot filesystem from ext4 back to ext2, since petitboot does not support ext4.
- ppc64el: create a separate ext2 /boot partition also for the non-LVM case, as it already is for LVM. So we support petitboot in all partitioning schemes.
partman-auto-lvm:
- Ensure the correct partitions are used (#1092129).
partman-base:
- Change default unit from MB to GB (#570410).
- Add support for the legacy_boot flag on GPT (#1034814, #1087489).
partman-efi:
- Rework EFI partition management logic (#1092978, #1092892, #1041168, #1034812, #1034208).
partman-partitioning:
- Add support for the legacy_boot flag on GPT (#1034814).
partman-xfs:
- Add support of "discard" mount option for XFS (#1092142).
- Add support of "prjquota" mount option for XFS (#1103244).
rescue:
- Add preliminary support for rescuing Debian installed to a btrfs subvolume (#1018894, #1103476). Supported rescue cases are:
  - The default installation to @rootfs (bullseye and later).
  - The default installation to subvolid=5 (buster or earlier).
systemd-udeb:
- Split udev-udeb and libudev1-udeb into a dedicated source package.
tzsetup:
- Replace legacy timezones with their modern counterparts (#1055541).
- Update cities/zones that have been renamed.
- Add templates for Cyprus.
user-setup:
- High-level summary: Restore support for non-ASCII fullnames (#1101069, #1101196, #1104550).
- Many more details are available in the user-setup 1.105 changelog entry for the curious. Lots of thanks to our longtime adduser maintainer, Marc Haber, and to the many who helped design then implement a plan (Pascal Hambourg in particular).
