[OE-core] [PATCH v5 0/7] #11662 - wic should mount /boot

[Ed Bartosh]

Hi,

This patchset adds /boot to the /etc/fstab of root partition, making
it mounted on boot. It also fixes reporting and testing issues
caused by this change.

The patchset also fixes long standing bug: wic updated fstab
inplace in rootfs directory. This causes other tasks working with
rootfs directory to produce incorrect results or crash. This is
fixed by hadlinking rootfs content to the temporary directory before
updating fstab.

This approach caused do_image_tar to fail with the error "file changed as we read it"
as hardlinking changes files ctime. In order to solve this we had to
modify do_image_tar to ignore file changes.

Changes in v2: squashed patches by reviewer's request
Changes in v3: unlink /etc/fstab in rootfs copy before updating it
Changes in v4: used 'cp -a' instead of copyhardlinktree to avoid
               do_image_tar failure due to changed ctime
Changes in v5: back to hardlinking. ignored tar exit code 1.

The following changes since commit b73f5e088a543775a2a94b60302f750edfffbd10:
