OpenSSL did not come from OpenBSD. OpenSSH was Tatu's SSH from the last
Free version, and maintained/developed since then by OpenBSD, so that
one's fair - the OpenBSD folks have certainly made a big contribution
(also including pf).

I would tend to NetBSD on a somewhat odd CPU. Most of the code is MI
and used/looked at by others, but the standaard exploits don't work. I
don't know what you mean by "powerpc is no longer updated enough"; that
seems to refer to perhaps a particular Linux distribution's practices.

This is a fair complaint (although the other side of the coin is that
I've seen people reinstall linux because they were scared of breaking
their system (or did)).
For NetBSD, there is code in pkgsrc/sysutil/etcmanage. With it, you can
basically check out the sources, run a build command (full build
including cross tools, can be done on amd64 for arm/ppc/etc.), and then
run an install command (that also updates files in /etc) and then
reboot. I do this all the time on many systems. This code should be
adaptable to OpenBSD/FreeBSD as well.

That's interesting that ksplice is repackaging Free updates and
charging; presumably one can redistribute the updates but the program to
apply them is non-Free. Still, that's going off the Free Software plan.,
When I look at all the problems I have, rebooting a machine every few
months is not a big deal.

I run tahoe-lafs from pkgsrc on a mac (including python, twisted, and
everything else needed). I don't worry about /usr/pkg/etc much; the
behavior on update is sane.
