Subject: [PATCH 2/5] tests: Prefer xorriso over genisoimage to generate
test.iso
This Debian page explains the upstream situation:
https://wiki.debian.org/genisoimage
On Fedora, xorriso provides a compatibility program called "mkisofs".
However this is not present in Debian. Hence the choice to look for
the program called "xorrisofs".

From efb8a766cac4ba8e413594946136bf91e176bb8c Mon Sep 17 00:00:00 2001
From: "Richard W.M. Jones" <rjones@redhat.com>
Date: Tue, 30 Mar 2021 13:54:22 +0100
Subject: [PATCH 3/5] daemon: Allow xorriso as an alternative to isoinfo.
Currently the guestfs_isoinfo and guestfs_isoinfo_device APIs run
isoinfo inside the appliance to extract the information.
isoinfo is part of genisoimage which is somewhat dead upstream.
xorriso is supposedly the new thing. (For a summary of the situation
see: https://wiki.debian.org/genisoimage).
This commit rewrites the parsing from C to OCaml to make it easier to
deal with, and allows you to use either isoinfo or xorriso.
Mostly the same fields are available from either tool, but xorriso is
a bit more awkward to parse.

From 2f587bbaec718e414e46c7e6f2a3e2662c3a1c2a Mon Sep 17 00:00:00 2001
From: "Richard W.M. Jones" <rjones@redhat.com>
Date: Wed, 31 Mar 2021 10:32:52 +0100
Subject: [PATCH 4/5] daemon: Read ISO9660 Primary Volume Descriptor directly.
It turns out we can read the information we need for the isoinfo API
directly from the ISO9660 PVD. We don't need to use either isoinfo or
xorriso. This also has the advantages of reducing by 1 the number of
dependencies in the appliance, and reducing potential vulnerability to
a crafted ISO file.
This also fixes timezone calculation for the datetime fields.
Thanks: Thomas Schmitt
Updates: commit efb8a766cac4ba8e413594946136bf91e176bb8c

From 278d0d3226f4bdb7c6586986ca46d0a25c976fe4 Mon Sep 17 00:00:00 2001
From: "Richard W.M. Jones" <rjones@redhat.com>

Subject: [PATCH 5/5] lib/appliance-kcmdline.c: Read UUID directly from
appliance.
Instead of using the external file utility, read the UUID directly
from the extfs filesystem. file 5.40 broke parsing of UUIDs
(https://bugs.astron.com/view.php?id=253).
Bug: https://bugzilla.redhat.com/show_bug.cgi?id=1945122
