# OK, there are some very old Linux standards that say that any binaries in a /bin or

# group root, unless a specific group is really needed for some reason.

# I can't find any mention of this in more recent standards docs, and always thought
# that it was pretty cosmetic anyway (hey, if there's a reason -- fill me in!), so
# it's possible that this ownership change won't be followed in the near future
# (it's a PITA, and causes many bug reports when the perms change is occasionally
# forgotten).

#
# No, no we won't.  You know how we love to break traditions.
