similar to: [PATCH] Add support for getting and setting GPT partition type GUIDs

GUESTFSD_EXT_CMD was used by OpenSUSE to track which external commands are run by the daemon and package those commands into the appliance. It is no longer used by recent SUSE builds, so remove it. Thanks: Pino Toscano, Olaf Hering. --- daemon/9p.c | 3 +- daemon/available.c | 7 +-- daemon/base64.c | 6 +-- daemon/blkid.c | 10 ++---

GUESTFSD_EXT_CMD is used by OpenSUSE to track which external commands are run by the daemon and package those commands into the appliance. However because this uses linker trickery it won't work from OCaml code. Replace it with a [nearly] standard C mechanism. Files still have to declare the external commands they will use, eg: DECLARE_EXTERNAL_COMMANDS ("btrfs",

Some OSes (e.g. Windows Server 2012 R2) fail to boot if the disk GPT GUID has changed.

add udev_settle calls to print_partition_table and sgdisk_info_extract_field because the inspect-os calls guestfs_part_get_parttype and guestfs_part_get_gpt_guid for all parition devices found and this causes intermittent with opening block devices that are certainly present yet RESOLVE_DEVICE macro would fail wiht ENOENT. --- daemon/parted.c | 9 +++++++++ 1 file changed, 9 insertions(+) diff

Check whether --part-type is supported (in the rewritten sfdisk in util-linux >= 2.26), and use it instead of --print-id & --change-id. The actual result should be the same, just not using a (recently) deprecated command line API. --- daemon/parted.c | 36 ++++++++++++++++++++++++++++++++---- 1 file changed, 32 insertions(+), 4 deletions(-) diff --git a/daemon/parted.c b/daemon/parted.c

Isolate in an own function the code that runs sgdisk and parse a field of it (using an extraction function passed as parameter), using it for the GUID type.

Counterpart of part-set-name, it uses sgdisk (hence needs the "gdisk" feature) to query for the label/name of a partition in a GPT layout. --- daemon/parted.c | 33 +++++++++++++++++++++++++++++++++ generator/actions.ml | 13 +++++++++++++ src/MAX_PROC_NR | 2 +- 3 files changed, 47 insertions(+), 1 deletion(-) diff --git a/daemon/parted.c b/daemon/parted.c index

virt-resize didn't preserve the per-partition GPT GUID. Now that guests using UEFI are becoming common (basically it's the default on aarch64) we need to take into account that sometimes the partition GUID is used by the bootloader NVRAM variables to identify the boot partition, so it must be preserved across resize. This bug caused the 'virt-builder --size' option to fail on

This action moves second(backup) GPT header to the end of the disk. It is usable in in-place image expanding, since free space after second GPT header is unusable. To use additional space, we have to move second header. This is what sgdisk -e does. However, sgdisk -e may perform additional actions if the partition table has unexpected params (e.g. if we call sgdisk -e /dev/sda1, it may fix

Create a new TestRunOrUnsupported test type, which represents a test sequence where a failure with ENOTSUP in the last command only marks the test as skipped.
