What I lean towards is the following:
1) Add a 'rescue' directive in kickstart for the sake of completeness (see
above), but without any options.

2) Add a new directive in kickstart so it describes what partitions and where to
mount them (as described in previous e-mail).

3) In rescue mode based on 2) try to mount the partitions.

4) If 2) is not present in kickstart then try some defaults if they fail, don't
try anything else.

5) Execute the %post scripts after everything is done.

Upgrade mode can also be modified to use 2) if present.

It's a bigger change than the proposed one but I'd prefer adding all the bits
now instead of doing the defaults (or --nomount, --romount) for rescue mode  and
later (not known when) adding the support for multiple roots.

Thanks,
Alexander.
