Why not introduce a new syscall(?) to dynamically query the username length,
where the setting is set by the admin? (Maybe in /etc/system, maybe somewhere
else) That way programs have an option of being compiled in a future safe
method. New programming guidelines would recommend that developers change to
the new methods. The syscall settings default would be set to 8 bytes by
default.
New functions don't help old applications.
A syscall here isn't actually the correct way to do it anyway since for
the most part the kernel doesn't deal in usernames only uids.
