I find one, probably minor issue with the installer.sh script. On the line: chown -R mobile /private/tmp/MediaCache near the end, the directory /private/tmp/MediaCache does not exist in my iPod but the /private/var/tmp/MediaCach does exist. Should that line be modified? Also when doing /dmg2img -v /private/var/decrypted.dmg /private/var/disk0s1.dd then if I do ls /private/var/disk0s1.dd I get file not found, so I am not sure what is going on. If I change disk0s1.dd to disk0s1 in the script and in the com.devteam.rm.plist file then /private/var/disk0s1 is created and the install.sh script works without any problem.
