First of all, bash and glibc are both fairly large chunks of code.
There are much smaller shells available, and there is at least one
miniature libc intended for embedded use.
Secondly, how are you booting the fs? ramdisks (including initrd) are
fairly wasteful of memory if used as a root filesystem; ramfs for
writable data and cramfs for a static boot fs are much better choices.
Cheers,
Stephen
