I entered the command you specified and the permissions on my Quadra are
identical to those on your system.   All of the files show root as owner,
just like on your system.  The executables, users and who, belong to the
wheel group, and the other two files, utmp and utmpx, belong to the utmp
group, just like on your system.

I also typed this command:
cat /var/run/utmp

Response was:
ttyE0root

Typing: cat /var/run/utmpx

Gave this response:
utmpx-1.00
roottyE0ttyE0K

Hmmm, bizarre.   The files don't appear to be empty.   Any other ideas?

Thanks,
