The F24 lives don't contain a rescue kernel or generate the corresponding
grub entry (see
https://bugzilla.redhat.com/show_bug.cgi?id=1317709 ). Is
there a way to install the rescue kernel if it was not done during the
initial install? (The package dracut-config-rescue was not installed, and
I've installed that manually.) I've nominated this bug as a FE, but it would
be less important if there's a way to fix the problem after install.
