Since wic image creation will temporarily update rootfs/etc/fstab to add UUID (*temporarily* means rootfs/etc/fstab will be recovered after wic image creation), there is a potential racing risk with other image creation (such as tar, ext)
Such as UUID was unexpected in tar.bz2's fstab: $ cat unpack_tar_bz2_dir/etc/fstab ... UUID=219B-2933 /boot vfat defaults 0 0 ... Explicitly make do_image_wic depend on other do_image_XXX (listed in IMAGE_FSTYPES except do_image_wicXXX) to avoid potential racing Signed-off-by: Hongxu Jia <[email protected]> --- meta/classes/image_types_wic.bbclass | 1 + 1 file changed, 1 insertion(+) diff --git a/meta/classes/image_types_wic.bbclass b/meta/classes/image_types_wic.bbclass index 96ed0473ee..79bafeb818 100644 --- a/meta/classes/image_types_wic.bbclass +++ b/meta/classes/image_types_wic.bbclass @@ -25,6 +25,7 @@ def wks_search(files, search_path): WIC_CREATE_EXTRA_ARGS ?= "" +IMAGE_TYPEDEP_wic += "${@' '.join('%s' % r for r in d.getVar('IMAGE_FSTYPES').split() if not r.startswith('wic'))}" IMAGE_CMD_wic () { out="${IMGDEPLOYDIR}/${IMAGE_NAME}" build_wic="${WORKDIR}/build-wic" -- 2.18.2
