I think we need to build in some extra logic in ipsec_kversion.h, but
the most elegant want of doing that is to have some C method of
recognising a redhat kernel build automatically.

No. For now you will need to apply the nat-t patch. Work is being done
to merge KLIPS and NETKEY into one stack, at which point this will no
longer be needed. You can look at this work in the unstable openswan
tree (aka 3.0.x).

please fo. Most people need nat-t because they connect from behind NAT
wifi routers. Without it, openswan is next to useless. And in your own
described laptop case, you will need it yourself as well.

The proper call is to do nothing in the init scripts. Eg rip out the newhostkey
generation from the spec file. openswan will detect there is no default
RSA key when it starts, and then create one *in the background*
