scripts/lib/wic/help.py: Update Fedora Kickstart URLs

2021-11-21T11:41:39+00:00

The URLs describing Kickstart are no longer valid and do not redirect to the correct location. Update them with the correct location.

wic: Add --no-fstab-update part option

2021-08-20T07:53:03+00:00

When embedding a rootfs image (e.g. 'rootfs-dir') as a partition we might want to keep the stock fstab for that image. In such a case, use this option to not update the fstab and use the stock one instead. This option allows you to specify which partitions get the fstab updated and which get the stock fstab. The option matches the argument you can pass to wic itself where the same action is performed but for all the partitions. Example: part /export --source rootfs --rootfs-dir=hockeycam-image --fstype=ext4 --label export --align 1024 --no-fstab-update part / --source rootfs --fstype=ext4 --label rootfs --align 1024 (From OE-Core rev: ab4c95af8ecd15dc136194ab761afae756db5803) Signed-off-by: Daniel Gomez Signed-off-by: Richard Purdie

Add support for erofs filesystems

2021-05-31T13:31:01+00:00

Since Linux 5.4 a new read-only filesystem is available, erofs. Compared to squashfs it offers much better read performance with and without compression enabled. It suppports two optional compressors, lz4 and lz4hc. >From the mkfs.erofs man page: EROFS is a new enhanced lightweight linux read-only filesystem with modern designs (eg. no buffer head, reduced metadata, inline xattrs/data, etc.) for scenarios which need high-performance read-only requirements, e.g. Android OS for smartphones and LIVECDs. It also provides fixed-sized output compression support, which improves storage density, keeps relatively higher compression ratios, which is more useful to achieve high performance for embedded devices with limited memory since it has unnoticable memory overhead and page cache thrashing. This commit adds support for three new filesystem targets: erofs: erofs without compression erofs-lz4: erofs with lz4 compresssion enabled erofs-lz4hc: erofs with lz4hc compression enabled (From OE-Core rev: 41dead1ff8ccc49e6cd6e6f5d41a59d164693e0d) Signed-off-by: Richard Weinberger Signed-off-by: Richard Purdie

wic: root: Add an opt. destination on include-path

2020-04-26T13:00:50+00:00

Allow specifying an optional destination to include-path and make the option aware of permissions and owners. It is very useful for making a partition that contains the rootfs for a host and a target Eg: / -> Roofs for the host /export/ -> Rootfs for the target (which will netboot) Although today we support making a partition for "/export" this might not be compatible with some upgrade systems, or we might be limited by the number of partitions. With this patch we can use something like: part / --source rootfs --fstype=ext4 --include-path core-image-minimal-mtdutils export/ --include-path hello on the .wks file.

wic: Add --change-directory argument

2020-04-26T13:00:50+00:00

This option allows to specify which part of a rootfs is going to be included, the same way the -C argument on tar. Thanks to this option we can make sure the permissions and usernames on the target partition are respected, and also simplify the creation of splitted partitons, not neeting to invoke external vars or using .wks.in files. Eg: part / --source rootfs --ondisk sda --fstype=ext4 --exclude-path=etc/ part /etc --source rootfs --fstype=ext4 --change-directory=etc Cc: Paul Barker (From OE-Core rev: 2265d089a58e1f78f26d623ee667c420cb1c3bd4) Signed-off-by: Ricardo Ribalda Delgado Signed-off-by: Richard Purdie

wic: Add --embed-rootfs argument

2020-04-06T15:45:11+00:00

This option adds the content of a rootfs on a specific location on the rootfs. It is very useful for making a partition that contains the rootfs for a host and a target Eg: / -> Roofs for the host /export/ -> Rootfs for the target (which will netboot) Although today we support making a partition for "/export" this might not be compatible with some upgrade systems, or we might be limited by the number of partitions.

wic: align layer plugin path

2020-04-02T14:24:59+00:00

wic look for external layer source plugin under scripts/lib/ while other tools look for lib/. allow wic to check for source plugin at both scripts/lib/ and lib/ to align with other tools while avoid breaking any existing source plugin in external layer.

wic: Add --include-path argument

2020-01-10T21:18:22+00:00

This option adds the contents of the given path to a partition built with the rootfs source plugin. The path is relative to the directory in which wic is running not the rootfs itself so use of an absolute path is recommended. This option is most useful when multiple copies of the rootfs are added to an image and it is required to add extra content to only one of these copies. This option only has an effect with the rootfs source plugin. (From OE-Core rev: d4cd27a9837426e809190548a83c6c7c76505114) Signed-off-by: Paul Barker Signed-off-by: Richard Purdie
