/lib/network/ppp.sh fixes a problem with PPtP (and other PPP-based things) where PPtP + PPPoE will fail to work. This is because PPtP defaults to ppp0 and so does PPPoE, because /etc/init.d/ppp reinitializes the unit counter for each PPP-type connection (so you could have multiple PPtP over cable, for instance, but PPPoE + PPtP is a problem).
/etc/init.d/ppp automatically starts pptp session on boot., from #6720 SVN-Revision: 20221
