Live CD does not have a troubleshoot boot sub menu option. This is
available with non-lives like DVD and netinstall images. The "rescue a
system" option uses the 'rescue' or more recently the 'inst.rescue'
boot parameter, which tells anaconda to run the text rescue mode, and
all of that code is found in anaconda and python-blivet.
