  62 # ubuntu is more user friendly when using multiple users. However,
  63 # it also makes it so if you create a file as a regular user then move
  64 # it to become a system file, it's got slightly wrong permissions, and
  65 # sometimes thing break. Also, copying files between ubuntu and debian
  66 # makes things inconsistent. So stick with 022 umask always.

  68 # One security concern is where some unixes put every user in a same
  69 # group, so if you copy files there with exact perms, that is probably
  70 # not what you want. I don't use a system like that, so I don't
