bash# cd /usr/src/bash−3.0
bash# export CC="gcc −mcpu=i386"
bash# ./configure −−enable−static−link \
−−enable−minimal−config −−host=i386−pc−linux−gnu
bash# make
bash# strip bash
2.3.10. Copy BASH to the root disk
bash# mkdir /mnt/bin
bash# cp bash /mnt/bin/bash
bash# ln −s bash /mnt/bin/sh
2.3.11. Create device files that BASH needs
