I'm hoping that you've now got your machine back---which is the first
priority.  'sulogin' (Single-User Login) is the program that would ask for a
password with the username forced to be 'root'.

I'm interested in debugging this either way;  as either it's an issue that
is going to bite people at the worst possible time (when their machine is
down and out for the count), or we can attribute this to a set root

Could you paste the output from the following:

  sudo grep root: /etc/shadow | tr '[0-9]' 0000000000

the 'tr' part of the command will obscur any numbers in the password-hash
---if there is one (somebody eager may to want to run 'John' on the hash!).

Why do one side of a triangle when you can do all three.   Nottingham, GB
