A slight variation on this could also provide for a permanent resolver
options configuration. One way would be to place just the options in
a file, say /etc/resolv.opts, and use the above script with the first
line replaced by "cp -a /etc/resolv.opts /etc/resolv.conf" so that
the options would be retained as well as the DNS nameservers added.
I think the last line could then be omitted (or replaced by the first
line but using ">>" instead of ">").

Since it is a comment, the first line should really begin with a "#",
but perhaps the resolver library just ignores something it doesn't
understand at all.

There are also distributions that don't use /etc/ppp/ip-up.local, and
the body of the script then should be a part of /etc/ppp/ip-up.
