Given the amount of currently open bugs in the Trixie Alpha 1 installer
(encrypted swap partitions, RTC/timezone, partition table flags, wrong
efi partitions...) I think the errata page
https://www.debian.org/devel/debian-installer/errata
should be completed with a reference to the debian-boot list.

Example wording:

"Please note that other problems may be found in the installer during
its testing: you are invited to check the debian-boot mailing
list https://lists.debian.org/debian-boot/ for an up-to-date status
on current bugs and possible workarounds."
