I looked at picobsd once...I remember thinking that it wasn't quite what
I was after.  Glancing quickly through the manpage it seems like it's
similar to m0n0bsd in that it has a compressed MFS root filesystem, and
therefore doesn't require the boot media after the kernel is loaded.

nanobsd (/usr/src/tools/tools/nanobsd) is designed to do a "normal"
UFS/UFS2 filesystem that lives on a flash drive or similar.  This
requires a larger flash device (each copy of my root partition, as
configured, could fit in a 64MB device, maybe less if I put some effort
into crunching things down).  However it is extremely easy to customize
because I don't have to deal with compressing and recompressing
filesystem images to make a change.

So for me, nanobsd seems to fit a little better with what I have in
mind.  Mine's been up and running for a couple months now, and aside
from a memory leak in if_bridge with PF (recently fixed in RELENG_6) all
seems to work well.

Right.  I'm interested (as are, I'm sure, a lot of FreeBSD committers)
to see what the performance measurements turn up.  For my setup,
downloads through my net4801 (filtering bridge with a few dozen PF
rules) can saturate my 6 Mbps DSL downlink.  This is of course not a
very high bar!  Anyways, once a few numbers have come in with the
prototype(s), I think it'd be useful to make a post to net@.  If there
turn out to be some bottlenecks, that's the crowd to work with.

Cheers,

Bruce.
