For /usr/sbin/ppp, you must choose between running ppp in the background or

connecting to a host immediately in the foreground.

I would like to be able to run ppp from a script so that my script can be
sure that it is connected to the 'net before it continues running:

  # Dial up the internet.
  ppp -background myprovider || exit 1

  do-some-net-command

  # Hang up the modem.
  kill -HUP `cat /var/run/ppp.tun0.pid`

Another problem is that the current ppp calls its process id file
`/var/run/PPP.server', which may conflict if you have more than one IP
tunnel interface available.

Closes PR#1469
