wic: add wks file to make use of exclude-path functionality

2018-03-06T14:35:42+00:00

Using --exclude-path and a wks.in file we can create an image that takes the /boot/ directory for the boot partition, has an empty /boot/ directory in the rootfs partition. The boot partition gets mounted to /boot/ after startup. (From OE-Core rev: db904053e8ee80fb6930c5e7e22287927e0f25e2) Signed-off-by: California Sullivan Signed-off-by: Richard Purdie

wic: Set a miniumum FAT16 volume size.

2018-03-04T11:35:40+00:00

Set a miniumum FAT16 volume size because images are not valid to parted if this minimum value is not respected. The value set is determined experimentally forr a logical sector size of 512. This fixed my local problem but, there may be better solutions.

wic: partition plugin wrongly assumes it is rootfs

2018-03-04T11:35:40+00:00

The partition plugin is used as the base for other plugins. One of the methods the plugins use, is the prepare_rootfs method. The prepare_rootfs method wrongly assumes that the value ROOTFS_SIZE from bitbake datastore is relevant to every invocation of prepare_rootfs, which it clearly is not, for example in the bootimg-partition case. This commit adds an optional argument to prepare_rootfs where a caller can tell prepare_rootfs if it is an actual rootfs and whether related rootfs information retrieved from bitbake is valid. The default behavior of this optional argument is to assume that the invocation is an actual rootfs, to maintain compatibility with previous implementations.

wic: Add post operation hook for SourcePlugin

2018-03-04T11:35:40+00:00

do_post_partition hook is needed if some operations like security signing the parition needs to be done. source plugins can make use of this to implement post operatiosn in do_post_partition. do_post_partition is called after do_prepare_partition if present.

wic: if we can't get from ioctl, try from os.stat()

2018-01-14T09:11:57+00:00

Under some conditions, ioctl FIGETBSZ can't return real value. We can try to use fallback via os.stat() to get block size.

wic: Fix a path to a psuedo state directory (PSEUDO_LOCALSTATEDIR).

2018-01-02T17:24:37+00:00

In case of 'new_rootfs' the psuedo directory is not copied. Thus PSEUDO_LOCALSTATEDIR should still point to the dsa 'native_sysroot'/../pseudo. Otherwise PSEUDO_LOCALSTATEDIR points to a not existing director ('new_rootfs'/../pseudo) and UID and GUID attributes are not applied to files of the image.

wic: Introduce --fsuuid and have --use-uuid make use of UUID too

2017-12-18T18:03:58+00:00

First, allow for wic to be given a filesystem UUID to be used when creating a filesystem. When not provided, wic will generate the UUID to be used. Next, when --use-uuid is passed, we update the fstab to mount things via UUID (and if not found, then use PARTUUID) as UUID is more portable.

wic: partition.py: Update comments slightly

2017-12-18T18:03:58+00:00

First, we support squashfs as root, so mention that. Second, the btrfs rootfs creation function had a copy/paste of the previous function comment, remove the irrelevant line.

wic: support filesystem label for rawcopy

2017-12-10T22:45:19+00:00

The '--label' argument should work for '--source rawcopy' as it does for '--source rootfs', so add a method in RawCopyPlugin to update the label on the temporary filesystem images.
