Jeff,

Thanks for the suggestion! Both machines have a umask of 0022 for  
root. Your suggestion pointed me to finding my error. I was checking  
to see that the files had the same SELinux context (ls -Z) as this  
has been an issue in other things. In doing so, I finally noticed  
that the machine with the device permissions of 666 also had an older  
udev rule (presumably from an earlier version). That rule was:

     KERNEL="fuse", NAME="%k", MODE="0666"

and named "40-fuse.rules" so it sorted ahead of the newer rule. When  
I copied this onto the machine with the newer installation, things  
worked as I expected. :)

Thanks again,
S
