Re: BeastieBox, a (Net)BSD BusyBox-like

I think your best result might be improving -DSMALL for some of

Of course any -DSMALL work helps almost everyone using NetBSD
in embedded work and even people trying to fit install binaries
on small media or memory systems :)
That's absolutely what I have in mind, I only choose other sources when
there's no other choice, at this time 99% of my work is 4.0 based and from
what I've seen I feel like it wouldn't change that much using 5.0.
Right, I had one old binary left, my bad, correct result is 3.4M... which is
far too high considering that devices like Linksys WRT54G, Fonera and friends
have around 4MB of flash memory.
Thats not entirely a fair metric:
- My 4.4MB /rescue gzips down to 2.2MB, which means vndcompress(1)
could be a real win
- /rescue is intended for recovering a broken system, so many
binaries could be dropped for an embedded one. From the start of
"ls /rescue | xargs which | xargs ls -s | sort -rn"
would just save 800K+ and even leaves in tetris! :)
- None of the numbers I've quoted above were with -DSMALL, plus
Thor's previous comments about making -DSMALL work for libc and
others could gain a lot
My gut feeling would be tuning the set of binaries and some
work with -DSMALL could get your 3.4MB down to 2.5MB, and
vndcompress(1) could get that down to 1.25MB. Granted, thats
not as good as BusyBox, but thats all before you have to go
outside the NetBSD source tree :)
I think BeastieBox could end up being very interesting..
good luck and have fun :)
