ppp link always dials when started with -auto?

With lots of help from John Chung I eventually fixed this problem - it was
because ipv6 was configured. I've disabled that in the kernel (I survived
without it for years, so no reason to have it as part of my upgrade).
I clocked up about 15 hours trying to debug this problem - that would have
been cut down to about 30 mins had this been in the FAQ. Can someone
please add this side effect of ipv6 on ppp to FAQ 14.17 or alternatively I
am happy to volunteer to do it myself?
There again if someone knows a cunning way to make ppp and ipv6 sit
happily together that might be a better way forward...
