wic: Introduce the --use-label partition parameter

2018-09-13T06:42:28+00:00

We can use this parameter to make the wic use the label to name a partition in /etc/fstab. (From OE-Core rev: 51638edaa00befaed58e2def255d46ae44d9234f) Signed-off-by: Kevin Hao Reviewed-by: Tom Rini Signed-off-by: Richard Purdie

wic: Remove the unused variable Partition.sourceparams_dict

2018-08-15T20:45:58+00:00

We choose to pass the source parameters to the source plugins' hooks via a local variable srcparams_dict. So the Partition.sourceparams_dict is not used by anyone and seems pretty confused. So drop it. (From OE-Core rev: d7130a7d0e61021f71fec1d7ae7d37ebb27f0e03) Signed-off-by: Kevin Hao Signed-off-by: Richard Purdie

wic: Fix partition files UIDs on multi rootfs images

2018-05-22T12:13:32+00:00

When a wks makes reference to multiple rootfs, libspeudo data is not properly chossen. This results in filesystems with invalid UIDs for all the files. This can be tested with this .wks file: part / --source rootfs --fstype=ext4 --rootfs-dir=core-image-base part /mnt/data1/ --fstype=ext4 --source rootfs --rootfs-dir=core-image-minimal part /mnt/data2/ --fstype=ext4 --source rootfs --rootfs-dir=core-image-minimal And this script $bitbake core-image-minimal core-image-base syslinux $losetup --partscan --find --read-only --show test*direct $sudo mount /dev/loop0p1 /mnt $ls -lan /mnt otal 40 drwxr-xr-x 18 0 0 1024 May 11 16:11 . drwxr-xr-x 25 0 0 4096 May 6 06:31 .. drwxr-xr-x 2 1000 1000 3072 May 11 15:51 bin drwxr-xr-x 2 1000 1000 1024 May 11 13:59 boot drwxr-xr-x 2 1000 1000 1024 May 11 13:59 dev drwxr-xr-x 25 1000 1000 3072 May 11 15:51 etc drwxr-xr-x 3 1000 1000 1024 May 11 13:59 home drwxr-xr-x 6 1000 1000 3072 May 11 15:51 lib drwx------ 2 0 0 12288 May 11 16:11 lost+found drwxr-xr-x 2 1000 1000 1024 May 11 13:59 media drwxr-xr-x 3 1000 1000 1024 May 11 15:50 mnt drwxr-xr-x 2 1000 1000 1024 May 11 13:59 proc drwxr-xr-x 2 1000 1000 1024 May 11 15:51 run drwxr-xr-x 2 1000 1000 3072 May 11 15:51 sbin drwxr-xr-x 2 1000 1000 1024 May 11 13:59 sys drwxr-xr-t 2 1000 1000 1024 May 11 13:59 tmp drwxr-xr-x 10 1000 1000 1024 May 11 14:54 usr drwxr-xr-x 8 1000 1000 1024 May 11 14:55 var $sudo losetup -d /dev/loop0 (From OE-Core rev: 450335ba5e73a375eb9932b4c4cf37979640dbfc) Signed-off-by: Ricardo Ribalda Delgado Signed-off-by: Ross Burton 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: 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.

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: add 'part-name' argument for naming GPT partitions

2017-11-07T13:25:31+00:00

The WIC's 'part' can now give a name for GPT partition in WKS file. It's similar to '--label', but is naming partintions instead file systems. It's required by some bootloaders to partitions have specified names.
