When a file is created, it is owned by the person who created it.
If you logged into a kfs system using a user name that was
not in /adm/users, then to kfs you are logged in as `none'.
If you are using a tool that sets the owner of a file
on a kfs system in allow mode, then kfs does not check
that you ask for a valid uid. If you ask for a user not
in /adm/users, it will use `none'.
The file server kernel and fossil are both much more
paranoid -- they will not let you log in and will not let
you chown when the users don't exist.
Kfs was never meant to be more than a crutch. The fact
that it is the most commonly used file server on Plan 9
is little more than an unfortunate historical accident.
