[Libguestfs] [PATCH] inspection: Handle MD devices in fstab

This patch fixes inspection when fstab contains devices md devices specified as /dev/mdN. The appliance creates these devices without reference to the guest's mdadm.conf so, for e.g. /dev/md0 in the guest will often be created as /dev/md127 in the appliance. With this patch, we match the uuids of detected md devices against uuids specified in mdadm.conf, and map them appropriately when we encounter them in fstab. The test in this patch also checks that devices specified by their md name, e.g. /dev/md/boot, work correctly, although the patch isn't required for devices specified this way. --- regressions/Makefile.am | 1 + regressions/test-inspect-fstab-md.sh | 65 ++++++ src/inspect.c | 22 ++- src/inspect_fs_unix.c | 411 ++++++++++++++++++++++++++++++---- 4 files changed, 456 insertions(+), 43 deletions(-) create mode 100755 regressions/test-inspect-fstab-md.sh
