Reducing libc size
In embedded environments, space is always scarce - be it physically,
for storage (disk/flash space), or for for computer memory.
Mikko Rapeli has made that experience with NetBSD, and
posted his solution,
which is to reduce NetBSD's libc in size -- see
his documentation!
Jörg Sonnenberger
pointed out
that another possible approach to save both diskspace and also (to some extent)
RAM when running executables is not to use shared libs, but to use
NetBSD's "crunchgen". Crunchgen statically links multiple binaries and their
libs into a single executable, saving diskspace and RAM -- exactly
what "busybox" does in the Linux world,
just highly configurable and working
with any sources. This is a
very cool feature of NetBSD, which is used to prepare the
install media from src/distrib, but it's also a very undocumented area
of NetBSD. Any takers for a "beastybox" article? :-)
