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.
