Great find (about the ~exec command). Obviously a stupid bug, left-over from firmware debugging. Crrrrrazy stuff! A simple jailbreak script (jb_install.sh) will be something like:
Code:
#!/bin/sh
export PATH=/usr/sbin:${PATH}

_FUNCTIONS=/etc/rc.d/functions
[ -f ${_FUNCTIONS} ] && . ${_FUNCTIONS}

mntroot rw

#install key
cat <<EOF > /etc/uks/pubhackkey01.pem

-----END PUBLIC KEY-----
EOF

mntroot ro
And that's all of it!

The instructions:
1) Copy jb_install.sh into kindle's main storage
2) ;debugOn
3) ~exec /mnt/us/jb_install.sh
4) No reboot needed
