@WarheadsSE: Ah Ok, thanks for the info.
@Razrael: Cool info thanks!
But in the end I just grabbed an old (1G!!!) USB stick and put a new install on that. One chroot later and my SD card is back to running. I'm keeping that stick for any future unexpected breakages...
Thanks and cheers to everyone!
(...and now I'm wondering if this thing - rendering a system unbootable even in single-user mode - would even be possible with the old rc script startup, but I don't know enough about systemd to make a coherent argument either way...)
