How many combinations do you plan to ship? I don't think it
At this moment, there are 3 builds take place (for 1.5):
with US domestic crypto
with international crypto
now you propose to do 6 builds:
IPv4-only without crypto
IPv4-only with US domestic crypto
IPv4-only with international crypto
IPv4/v6 without crypto
IPv4/v6 with US domestic crypto
IPv4/v6 with international crypto
I really vote for IPv4/v6 distribution only. Also we should
integrate crypto-ready distributions into one, to make only 2

how much size increase is "bloat" for you? for example:
-rwxr-xr-x 1 root itojun 109476 Apr 20 12:28 obj/pppd.v4
-rwxr-xr-x 1 root itojun 117476 Apr 20 12:29 obj/pppd.v6
If many REALLY care, I think it can be done, but I don't really
like this due to maintenance headaches.
- enable IPv4/v6 for kernel and userland by default
- ship IPv4/v6kernel in kern.tgz
- make a separate distribution set "base6.tgz" which contains
IPv6-only tools like route6d or ping6.
base6.tgz will be real small, it will contain only the following
files. I think the base/base6 split is not necessary.
manpages for them
