Hi,

I ran into an issue using the /tmp directory. We are using the exec driver and the code running in there is Ruby.

We are trying to use the method Dir.mktmpdir, but it fails. Looking at the implementation it expects the /tmp directory to be sticky, which it's not currently.

def Dir::tmpdir
  if $SAFE > 0
    tmp = @@systmpdir
  else
    tmp = nil
    for dir in [ENV['TMPDIR'], ENV['TMP'], ENV['TEMP'], @@systmpdir, '/tmp', '.']
      next if !dir
      dir = File.expand_path(dir)
      if stat = File.stat(dir) and stat.directory? and stat.writable? and
          (!stat.world_writable? or stat.sticky?)
        tmp = dir
        break
      end rescue nil
    end
    raise ArgumentError, "could not find a temporary directory" if !tmp
    tmp
  end
end

What do you say about setting the sticky attribute?
