Just another example of physical security being important.
Good try... except that Apollos do not use /etc/passwd files. (They use the
registry daemon rgyd, the /etc/passwd file being a read-only object provided
for compatibility with brain-dead UNIX utilities only.) Besides, if you had
set sensible permissions on your file system, then you should not be able to
modify anything (let alone /etc/passwd) from Apollo's "PhaseII Shell" (the
single-user mode) where you run as user.none.none.
