You can still use an earlier 1.x version of bash which is linked to
libtermcap.
It will be much smaller and you probably don't need much functionality in
your 
shell if you're just setting up networking and running simple scripts.

My bash, from the yellowdog distro, stripped, is about 400k.
If you're worried about space, strip all your binaries and libraries, 
and look at possibly using a more minimal shell like ash.
