Hi Jerry et all,
Below is a review of your patch:

This is not correct, we may need to unmount stage2 when it is an install CD / DVD
as we may need to change DVD / CD as the needed packages may be split over multiple
disks.

So you're hardcoding the use of /tmp here, but there are no ideas /tmp is a
good candidate in case of an upgrade it might even be a tmpfs for people who
have modified their fstab to make it such.
You are on to something here, the old code is using the first
element of anaconda.id.storage.fsFreeSpace, which is sorted by size, but
that is the element with the smallest size! I think this is a bug and the
code should use the last element

Not sure what you are trying to do here, self._loopbackFile is None (so false)
the first time we go through this code path, and if we go through this code
path multiple times, it should be a nop the second time (see the
check for this you removed above).

Ok, you've alsmost completely lost me here, I have some clue what
you are trying to do, but it is completely unrelated to the previous parts
of this patch.
Please make *ONE* change per patch, and add a lot more verbose description
of the why, what and how of the patch. So put in the description:
1) What you are trying to fix
2) What is the current behaviour (if applicable in various scenarios)
3) What are you changing and how does this fix this.
4) How does this change impact other install scenarios ?

Again, this seems yet another changed put in one and the same patch without any
explanation. Please split this patch up and thoroughly explain the reasoning behind
the patch. Also it seems wrong, as you are now transfering the image to HD, even when
we are doing a single dvd install, eating all that precious hard disk space you
are trying to avoid us running out of.
Regards,
Hans
