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: 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: 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.

wic: fix calculation of partition number

2017-07-21T21:51:37+00:00

Total number of partitions should be taken into account when calculating real partition number for msdos partition table. The number can be different for the 4th partition: it can be 4 if there are 4 partitions in the table and 5 if there are more than 4 partitions in the table. In the latter case number 4 is occupied by extended partition.

wic: fix restoring of original fstab

2017-06-23T10:44:12+00:00

Wic updates fstab if mount points are specified in .wks. After partition images are created the original fstab is restored. However, if exception is raised when partition image being prepared wic doesn't restore original fstab. This can cause duplication of added lines in fstab when 'wic create' runs next time. Wrapping call of 'prepare' method and restoring original fstab even if exception occurs should fix this.

wic: flatten directory structure

2017-06-23T10:44:12+00:00

filemap: change signature of sparse_copy function

2017-06-14T09:18:29+00:00

Renamed parameter offset->skip to match names of dd parameters. Changed affected sparse_copy calls. Added explanation of the parameters to docstring. (From OE-Core rev: 08e2f4e59816c5757686255b267b08cbc46fbd95) Signed-off-by: Ed Bartosh Signed-off-by: Richard Purdie

wic: set correct system id for msdos partitions

2017-04-01T07:14:58+00:00

Explicitly set system id 0x6(FAT16) for msdos partitions. Removed old code that attempts to achieve the same result using 'parted ... lba off'. (From OE-Core rev: 230452faf151e277bfb2b49526923f8097755b35) Signed-off-by: Ed Bartosh Signed-off-by: Richard Purdie

wic: allow only supported fstypes

2017-04-01T07:14:57+00:00

Restricted possible values of --fstype to the list of supported types. This should catch incorrect values when .wks file is being parsed. Removed checks for empty fstype and mentioning of unsupported fstype 'ontrackdm6aux3'.
