ipv6 only host - problems (5.2-current)

hi,

i try to set up an ipv6 only freebsd 5.2-current system.

the fist issue is with the kernel:

i dont want an ip dual-stack, i want an ipv6-only ip stack...

so i confed my kernel like this:

#options        INET
options         INET6

and goit the following error when build kernel with

make kernel KERNCONF=... (world and kernel were up to date before):

-- possible bugfix : --

so i went on, and tried a work around by fixing: if_ethersubr.c
i just did #ifdef INET / #endif around the declaration of *sin
as it seems logical ?!

--

then i tried to compile the kernel again...
well it compiled everything,
but after that in the link-phase (99% finished) it went wrong...

--------

the other issue is that cvsup doesnt support ipv6, seems as no one likes 
modula source code, including me ;-)

syncvs supports it, but cant handle module checkouts... and i only wanna fetch 
src and ports, not the whole cvs server up and down ;-)

i dont know if this should be placed in this mailinglist, but where should i 
place it then?

so i still must find a good way to stay in sync with cvs with ipv6-only 
config... lets see...
