I'll have a go at reproducing Today or Tomorrow.

This is a shallow test: I didn't regenerate my initramfs first, but I (by coincidence) had to cold boot my desktop, so I gave it a go. I was able to SSH in and run cryptroot-unlock successfully.

dropbear-initramfs:
 Installed: 2025.89-1~deb13u1
Linux 6.16.9+deb14-amd64 #1

/etc/dropbear/initramfs/authorized_keys contains two entries, labelled
jon@phobos and jon@qusp (the latter of which my client issued)

The server does not have a /root/.ssh/authorized_keys so the initramfs has not picked it up from there (unless there's another place it could be hidden)

My initramfs dates from:

-rw------- 1 root root 129582334 Jan 11 14:36 
"/boot/initrd.img-6.16.9+deb14-amd64"

I'd wager that was triggered by installing 2025.89-1~deb13u1.

I'll try regenerating it later and see what happens.
