unless /var is nfs-mounted. This was removing ppps device lock (when ppp's started in /etc/start_if.tun0 in -ddial or -dedicated mode) and allowing other programs (such as mgetty) to confuse ppp by playing with the modem while ppp's using it. People that nfs-mount /var had better not start ppp in this way....
