if{up|down}-ppp

[Grzegorz Stanislawski]

Witam.
 Poniewaz pppd w pld-devel (2.3.5) ma kilka ciekawych funkcji, pozwolilem
sobie zmodyfikowac lekko odpowiednie skrypty z initscripts tak aby robily
uzytek przynajmniej z tej ktora mnie interesuje (persist).
 Demand dialing dorobie pozniej w wolnej chwili.
 ifcfg-ppp1 to przykladowa konfiguracja oczywiscie.
Jesli sadzicie ze sie to nadaje do wstawienia do initscripts.rpm niech
"maintainer" tego pakietu to zrobi.
