    I recently installed my first UEFI amd64 host. I used debian-installer to configure a brtfs root, which used the default @rootfs volume name.

    Contrary to what some people claim, UEFI is anything BUT "modern and robust" so I have had to use d-i's rescue mode off a USB stick or a regular basis. The USB stick currently contains:

    Debian GNU/Linux 12 (bookworm) amd64 - netboot mini.iso 20230607+deb12u9

    The rescue operation currently involves typing a complicated series of commands on the console, because d-i seemingly cannot work with btrfs volume names.

    IMHO, at the very least, the menu to select the partition to mount should show the output of 'lsblk -f'.

    Better yet, the rescue mode should be able to find the root and EFI partitions by itself and offer to mount them.

    A solution in-between could involve suggesting a disk among those found to have both an EFI partition AND a Linux partition whose label is '/' and mount these e.g. /dev/sda has both an EFI partition and a Linux partition labelled '/', would you like to
    mount them?

    That should obviously be: a disk containing both an EFI partition AND
    a Linux partition with a filesystem whose label is '/' (and, if btrfs,
    a subvolume named @rootfs).
