This saves us going into a loop if virDomainDestroyFlags keeps
returning -EBUSY quickly, which apparenrly can happen in containers.
The equivalent 'direct' backend code sleeps for 2 seconds in this case.
This is just code movement.

RWMJ: Renamed and moved the function for consistency with surrounding
code.
Many years ago we used to pass acpi=off on the Linux kernel command
line. In commit db1f811b2 we stopped doing that (around 2016).
However unless you also use:
<features>
<acpi/>
</features>
then it turns out that libvirt disables ACPI generation at the qemu
level. None of this mattered until SeaBIOS 1.17 changed its
behaviour, causing ACPI to be required for virtio devices to work.

This test has never been run. It was originally added in
commit 36d6df671e ("tests/http: Add a test of HTTP protocol.", 2013).
However even when it was added, it was commented out.

We removed the final uses of custom printf formatters in
commit 0b3c6cc0c0 ("daemon: Remove remaining uses of custom printf %Q

libosinfo changes the naming scheme it uses for SUSE starting with
major version 15. Previously it used names like "sles12" (or
"sles12sp1"), "sled12" for Server and Desktop variants. In 15+ it
uses "sle15" as there are no variants any longer (instead the
installer asks you what variant you want to install). We're only
interested in the Server variant. Change the name that we return to
"sle15" or "sle15sp1".

They will be removed in libguestfs 1.58 (the next but one version).
Currently they don't actually compile. The larger problem is that
they don't handle 64 bit quantities properly (using floats instead),
meaning that any disk size or offset above a certain size will be
improperly passed through the API, usually rounded to the nearest
53 bits.
In SLES guests in particular, btrfs snapshots seem to be used to allow
rollback of changes made to the filesystem. Dozens of snapshots may
be present. Technically therefore these are multi-boot guests. The
libguestfs concept of "root" of an operating system does not map well
to this, causing problems in virt-inspector and virt-v2v.
In this commit we ignore these duplicates. The test is quite narrow
to avoid false positives: We only remove a duplicate if it is a member
of a parent device, both are btrfs, both the snapshot and parent have
a root role, and the roles are otherwise very similar.
There may be a case for reporting this information separately in
future, although it's also easy to find this out now. For example,
when you see a btrfs root device returned by inspect_os, you could
call btrfs_subvolume_list on the root device to list the snapshots.

Back in commit 8289aa1ad6 ("New APIs for guest inspection.", 2010)
when inspection was first added, we did inspection in the library, so
it was accurate to say that inspection information was stored "in the
handle". Much later, in commit 394d11be49 and commit 3a00c4d179
(2017) we moved inspection to the daemon, but left the comment the
same.
Fixes: commit 3a00c4d179
This function is used from other parts of the daemon, especially for
example with inspection. However it was difficult to follow exactly
what filesystems it was returning because of insufficient debugging
information.
create.c: In function 'disk_create_qcow2':
create.c:372:5: error: format not a string literal and no format arguments [-Werror=format-security]

After this, output looks like
$ ./run guestfish --ro --format=qcow2 -a test.img

The old btrfs-fsck API used "btrfs check" which appears to be broken
or deprecated. The real tool you should use is "btrfs scrub". We
have already implemented that API, but it is very awkward to use from
libguestfs. In particular there's no existing way to run the scrub
and wait for it to finish.
Fix this by deprecating btrfs-fsck. Implement a new API
btrfs-scrub-full which runs btrfs scrub in the foreground, waits for
it to finish, and handles errors. It's much more like fsck tools in
other filesystems.

This pulls in the commits below, requiring us to replace all uses of
String.is_prefix and String.is_suffix.
Mostly done with Perl like this, and carefully checked by hand
afterwards since this doesn't get everything right:
$ perl -pi.bak -e 's/String.is_prefix ([^[:space:]\)]+) ([^[:space:]\)]+)/String.starts_with \2 \1/g' -- `git ls-files`
Richard W.M. Jones (3):
mlstdutils: Fix comment that still referred to the old function names
mldrivers: Link to gettext-stub if ocaml-gettext is enabled
mlstdutils: Rename String.is_prefix -> starts_with, is_suffix -> ends_with
Pull in these commits which require minor changes:
Richard W.M. Jones (3):
mlstdutils: Remove Std_utils.identity
mlstdutils: Remove Std_utils.protect
mlstdutils: Remove List.filter_map
Adds these commits:
Richard W.M. Jones (5):
mlstdutils: Modify List.take, List.drop to match OCaml 5.3
mlstdutils: Rename List.dropwhile -> drop_while, takewhile -> take_while
mlstdutils: Add List.last function
mlstdutils: Move List module first
mlstdutils: Add String.common_prefix, longest_common_prefix
zfs-fuse has been unmaintained for a very long time. In fact, the
website has gone. This means that whatever we need for zfs (probably
some kind of license-compatible kernel module) is not going to be
provided by zfs-fuse.

A customer case was found where /etc/fstab contained multiple root
mountpoints, something like:
LABEL=System / xfs ...
LABEL=Boot /boot ext2 ...
LABEL=System / xfs ...
This causes libguestfs and virt-v2v to fail. Either (on RHEL 9) we
try to mount the second instance of / which gives an error. Or (on
upstream kernels) we are able to mount the second instance but then
libguestfs gets confused when trying to unmount them.
In this case as the mounted devices are the same we can just delete
the duplicate. It's also possible that there could be multiple
non-identical root mountpoints, in which case we have to pick one, and
this code arbitrarily picks the first[*] (but emits a warning).
We don't do anything for non-root mountpoints.
Update common submodule to add 'List.same' function from mlstdutils.
[*] Which one is "the first" depends on what version of ocaml-augeas
we are using. ocaml-augeas version 0.6 Augeas.matches function
returns entries in reverse order (compared to augeas itself). This is
fixed in version 0.7:

We could match on 1- and 2-digit RHEL issues, thus matching strings
like "RHEL-9" and "RHEL-10". No such Jira issues exist for us.
(cherry picked from commit 846ecb2b3840212c6f2cad6a15a6b33cd2e912bf)
We didn't correctly check for an error from the ioctl. Thus when
using a raw block device you would often see a bogus warning in
debugging output.
