Kickstart installation - adding commands available at 'pre' time

I'm currently building a kickstart cd, and it's all ready to go except...the script I'm using in the 'pre' section needs to commands (bc and expr), that arn't available by default in the stage2.img file.
Everything I've read tells me to just mount the file, add the commands I need, and all will be fine.
Whilst I can mount the img file, it appears to be mounted in a read-only mode, so whenever I try and add the commands to it, I'm just getting the 'permission denied' error:

# mount -o loop stage2.img j
# touch j/test
touch: creating `j/test': Permission denied
# umount j
# mount --o loop,rw stage2.img j
# touch j/test
touch: creating `j/test': Permission denied
#

mount does show the image file being mounted read/write:
/tmp/j/stage2.img on /tmp/j/j type cramfs (rw,loop=/dev/loop0)

Anyone got any bright ideas on how to add these commands to the img file?
500 points on offer, 'coz my new servers are due to arrive in about 3 hours or so, and I want to start getting linux installed as soon as possible!

Cramfs file systems are read only by nature.

There is a tool mkcramfs that creates a cramfs file.

What you would do is mount the original image. Copy the contents to an empty subdir elsewhere in the dir-tree. Add the stuff you want in the image and then mkcramfs <subdir> <filename>
