I was starting to wonder if it had something to do with the struct
ucred... this would make sense... esp. considering it's an MS-DOS
filesystem... i.e., it carries no user info on files.

FWIW, it's the same behaviour with -mapall=catseye as without (catseye
is the user who owns the /c directory, and mount_msdos treats that user
as the owner of all files under it, when it's mounted.)
