If the content is user-configurable as I suggested, the lvm tools could
be included in the rescue initd.
Remember, this initrd would not be loaded for normal use, only when one
might otherwise reach for a rescue CD.
Modern computer have heaps of RAM even to load quite a unrespectably
large image!
It might not help people with small computers; they just turn off that
functionality and proceed as before.
I'm digging around in the f9 netinst iso atm, trying to solve my kernel
problem. The initrd for this iso loads a 100 Mbyte or so ramdisk that
contains basically the rescue disk+installer. It shouldn't be hard to
copy this to the installed system and boot it from grub.
With the recover option, one would expect this might be regenerated as
new kernels (and tools) are installed.
