rc.boot file??

[GoogleCodeExporter]

Hello Jean,
do the tools use the default rc.boot file that msftguy's tool use?
or do the protection tools generate their own?

The reason I ask is, if I look at the mounted dmg (myramdisk.dmg) the rc.boot 
file seems to be encrypted. So I am unable to determine what is contained in 
the file.

However, if I mount the dmg file that msftguy's tools generate 
(038-5512-003.dmg) I am able to view the rc.boot file as a plain text file.

Thank You!
frank

The ramdisk is built by replacing the restored_external daemon on a stock Apple 
ramdisk.
The regular boot process on Apple ramdisk is /sbin/launchd -> /etc/rc.boot -> 
/usr/local/bin/restored_external. The default /etc/rc.boot is actually a mach-o 
binary that tries to execute the following binaries until one of them is found:
"/usr/local/bin/restored_external"
"/usr/local/bin/restored_update"
"/usr/local/bin/restored"
"/usr/libexec/ramrod/ramrod"

msftguy ssh ramdisk uses a different approach, where it replaces rc.boot with a 
shell script that runs sshd, and then starts Apple restore daemon (see 
https://github.com/msftguy/ssh-rd/commit/3fcb8e44512f3a1dd76dbb75566a6b35fd95812

You can see the source of our custom restored_external on the repository:
http://code.google.com/p/iphone-dataprotection/source/browse/ramdisk_tools/resto
red_external.c
It replicates functionalities from Apple restored (start usbmux, disable 
watchdog), starts sshd and then listens on port 1999 for commands from the 
python scripts.
