That's a rather odd corner case, even less likely IMHO than a missing
"root" user. I'm not too worried about it. Frankly, just add "root" to
your "passwd" file, and move on.
However we could instead write "-user 0", which will work on systems
where the user with uid 0 is called something other than "root". As
for systems with a spurious user "0", too bad IMNSHO. However, I'm
disinclined to recommend any changes to the current code.
