The problem here is that the 'eth0' interface is not up when pppd is
launched. This would be easily solved by running
 ip link set eth0 up
before launching pppd, but netcfg doesn't know that. I always planned to
write a 'pppoe' target for netcfg, but never did.

I can't think of a good workaround right now, maybe someone else has an
idea.

Seems fine.

You don't need pppoe.conf - you don't even need the rp-pppoe package.
You only need the ppp package and the peers/pap-secrets files as shown
above.

There is some more information in the HOWTO [1] I wrote years ago, but
much of it is outdated.
