why /sbin and /bin in netbsd is all static by default?
wouldn't be good to put libc and ld-elf.so to somewhere like /lib, do
links from /usr/lib to that file to avoid duplication and link all
dynamic.

i've already recompiled bin and sbin dynamic (without later steps as my
/usr is on / partition) on my 8MB notebook and it's much faster and
about few MB less diskspace!!!
