Unfortunately, that turned out to be a bit premature. After compiling a
kernel on it remotely over ssh (not interacting with the logged in
desktop), a reboot failed with endless completion-wait loop timeout
messages and after a force poweroff and restart it won't boot. The EFI
filesystem was even destroyed, probably because the kernel installation
modified a file on there.
