wic: improve generating disk system identifier

2017-08-03T10:14:13+00:00

This should reduce the chance of generating 0xffffffff as the disk system identifier. (From OE-Core rev: 5619e72facbc9228d3cf8f844f198e03b536ac8c) Signed-off-by: Jonathan Liu Signed-off-by: Richard Purdie

wic: Switch to using --use-uuid by default

2017-07-30T07:46:20+00:00

The most portable way to specifiy a root device in a disk image that we create is to use PARTUUID rather than /dev/sda2. As background, both GPT and MBR tables provide valid UUID values for each partition and the Linux Kernel contains the logic to parse this value. With this change we can now boot the default disk images when used as any valid block device that the included kernel uses. This for example means that VirtualBox can be used to run vmdk without changes as it uses IDE for the virtual disk controller.

wic: ensure generated disk system identifier is non-zero

2017-07-30T07:46:20+00:00

Zero may be interpreted as no MBR signature present and another partitioning program might install a new MBR signature. (From OE-Core rev: f53b5555d6eaa171bc5882cfee807cf62576862d) Signed-off-by: Jonathan Liu Signed-off-by: Richard Purdie

wic: add /boot mount point to fstab by default

2017-07-30T07:46:19+00:00

wic avoided adding /boot to fstab for no reason. This exception was hardcoded in the wic code. There is no need for this as mountpoint in .wks file is an optional field. It can be used only if user wants to have partitions automatically mounted on system boot.

wic: rootfs: make copied rootfs unique

2017-07-30T07:46:19+00:00

Used unique suffix (line number from .wks file) for the copied rootfs directory to avoid possible conflicts. (From OE-Core rev: 01efc234a8caab67ed3138ab2de9bbd82ce97b44) Signed-off-by: Ed Bartosh Signed-off-by: Richard Purdie

wic: rootfs: fix rootfs path reporting

2017-07-30T07:46:19+00:00

wic gets rootfs paths from partition object property 'rootfs_dir' and shows them in final report. rootfs plugin sets this property to the temporary path, which causes temporary paths appearing in the report. Changed the code to prevent storing temporary rootfs path in part.rootfs_dir. This should fix the report.

wic: use absolute paths in rootfs plugin

2017-07-30T07:46:19+00:00

Using relative paths can cause copyhardlinktree API to fail as it changes current directory when working. Converted all paths to absolute paths using os.path.realpath. (From OE-Core rev: a1c83cebe986e211dfc31be5cbd748f53fc298df) Signed-off-by: Ed Bartosh Signed-off-by: Richard Purdie

wic: copy rootfs directory before changing fstab

2017-07-30T07:46:19+00:00

wic updates /etc/fstab on root partition if there are valid mount points in .wks When wic runs from bitbake this can cause incorrect results or even breakage of other tasks working with the same rootfs directory in parallel with do_image_wic. Implemented copying rootfs directory to a temporary location using copyhardlinktree before updating fstab to avoid conflicts with other tasks working with the same rootfs directory.

This plugin will be removed starting 2.5 development in favour of using 'bitbake-layers create-layer' script/plugin, offering a single script to manage layers. (From meta-yocto rev: 76dd79e345d8edb22fc7aefd31f2a1f150916718) Signed-off-by: Leonardo Sandoval Signed-off-by: Richard Purdie
