I've working on this today, I don't have this issue. I have both a 
dial-in server and I dial out. I see the issue as lacking of 
configuration information in BLFS for /etc/ppp.

BLFS needs to reference all the materials in the PPP howto especially 
this information

So the issue is not the bootscripts, it's the way ppp is configured.
