If I remember correctly, rpm needs them. It's been a while since I added 
those files, so I'll have to test and see if that's correct. I know I had 
a good reason at the time. ;)

The binaries are linked against uClibc, a very small implimentation of 
libc.  http://www.uclibc.org/uClibc.html

What version of the installer are you using? Recent versions use the ash 
shell, which has much more functionality that the older versions, which 
used the busybox msh shell. I've found most 'bash' style syntax works as 
expected.

You mean a different shell? I'm willing to entertain the idea if it is 
small enough. I also want to make the system usable when booted from the 
installer floppy (as a rescue disk, for example) without having people 
stumbling over an unfamiliar shell.

I use a set of scripts to automate the build process. The scripts allow me 
to say:
./mkdisk1
./mkdisk2
./upload_slinky
