I don't think we have sufficient evidence to back that assertion yet.
Let's not jump to conclusions, maybe there is a real problem that might
impact on user somewhere.

I read your readme, but I can't figure out what "I" got wrong (esp.
given that I haven't even touched the confiuguration).

root at burroughs:/etc/udev # grep null *
permissions.rules:KERNEL=="null",               MODE="0666"
permissions.d/udev.permissions:null:root:root:0666
scripts/cdsymlinks.sh:  local DEVLS="`ls -dl \"/dev/$2\" \"/dev/$2
\"[0-9]* 2>/dev/null`"

There they are, 0666.  How did they end up generating files with 0660
permissions?

Why do you not want to co-operate with people who are contributing to
the package's bug discovery and bugfix process just because they use a
different base system?  Surely they are helping and not hindering.
