Debian Installer Bookworm RC 2 release

The Debian Installer team[1] is pleased to announce the second release candidate of the installer for Debian 12 "Bookworm".

Debian12

Improvements in this release
============================

* apt-setup:
- Enable -updates when installing testing, not only when installing (old)stable (#991947).
* argon2:
- Restore threading support in the installer (#1034696).
* base-installer:
- Install zstd alongside initramfs-tools, like busybox.
* choose-mirror:
- Update Mirrors.masterlist.
* cryptsetup:
- Improve support for low-memory systems (#1028250): Check for physical memory available also in PBKDF benchmark, and use only half of detected free memory on systems without swap.
* debian-cd:
- Include zstd alongside initramfs-tools, like busybox.
* debian-installer:
- Fix grub font loading, making sure we get the nice graphical splash screen in Secure Boot mode too (#1034535).
* grub-installer:
- Install shim-signed on i386 and arm64 as well as amd64 when we're installing grub-efi-*-signed packages.
- If we detect other operating systems installed, check with the user (at low priority) and re-enable os-prober.
* grub2:
- Add debconf logic for GRUB_DISABLE_OS_PROBER to make it easier to control things here, particularly useful for the installer (#1031594, #1012865, #1025698).
- Add luks2 to the signed grub efi images (#1001248).
- Fix probing of LUKS2 devices (#1028301).
- Fix Secure Boot on arm64 (#1033657).
- Don't warn about os-prober if it's not installed (#1020769).
- Fix an issue where a logical volume rename would lead grub to fail to boot (#987008).
* live-installer:
- Remove the live packages before the cdrom is unmounted, avoiding a long wait at the end of the installation process.
* partman-efi:
- Fix detection of BIOS-bootable systems, fixing at least the "Guided - use entire disk and set up LVM" use case on UEFI systems (#834373, #1033913).
* preseed:
- Restore support for the "hostname" alias on the kernel command line (#1031643, #1034062).
- Switch auto-install/defaultroot to bookworm.

Hardware support changes
========================

* flash-kernel:
- Adjust OLPC XO-1.75 boot script.
- Add Lenovo Miix 630 and Lenovo Yoga C630.
- Add StarFive VisionFive board.
- Add D1 SoC boards.
- Add QEMU-related "dummy" entries.
- Add A20-OLinuXino_MICRO-eMMC (#1019881).
- Add Lenovo ThinkPad X13s.
- Add Colibri iMX6ULL eMMC.
- Add Raspberry Pi 3 Model B Plus Rev 1.3.
* linux:
- udeb: add intel_lpss* (optional) to kernel-image (#1032136). Many laptops have their touchpad accessible over I2C, only visible if LPSS is available in the installer.
