[DistroKit] [PATCH v2 00/10] refactor data partition setup

[Roland Hieber]

PATCH v2:
* ENV{PARTNAME} is not set for all partitions, use
  ENV{ID_PART_ENTRY_NAME} instead, which is also used by udev's
  60-persistent-storage.rules to generate /dev/disk/by-partlabel/*

PATCH v1: https://lore.distrokit.org/distrokit/20231103182438.1051601-1-rhi@pengutronix.de

  treewide: images: unify partition labels
  v7a: image-stm32mp: set GPT Partition Type UUID
  treewide: images: remove size specifications for root partitions
  treewide: images: increase size of all qemu images to 1 GiB

[DistroKit] [PATCH v2 01/10] treewide: images: unify partition labels

[Roland Hieber]

The partition label is written to the GPT, and systemd-repart can match
on the partition label, which we'll use in a later commit. Set the name
of the first root partitions to the same name ("root-A") to give the
matching algorithm something to work with.

[DistroKit] [PATCH v2 03/10] treewide: images: remove size specifications for root partitions

[Roland Hieber]

With current rootfs sizes of below 200 MiB there is no need to have a
512 MiB root partition, which will be a lot larger than the file system
it contains, and which will also all have to be written to the SD card.
Let genimage determine the partition size based on the file system image
it contains, thereby reducing the size of the generated disk images.

[DistroKit] [PATCH v2 04/10] treewide: images: increase size of all qemu images to 1 GiB

[Roland Hieber]

qemu sets the size of the emulated disk as the size of the underlying
image file. We want to fit two rootfs partitions and one data partition
of 200 MiB each in there, which will need at least 600 MiB of disk
space. Round up to the next power of two, so qemu can work with it,
which results in 1 GiB, which the other qemu images already have too.

[DistroKit] [PATCH v2 05/10] datapartition: generate partitions via systemd-repart

[Roland Hieber]

Generating the second rootfs and the data partition on the first boot
has the advantage that the generated images can get even smaller, and we
can resize the data partition on-the-fly to fill the available space on
the boot medium.

Specify a minimum of 200 MiB for the first and second root partitions
just so that both are of equal size. (This will fit any root.ext2 in any
of our platforms with about 25% of space left.) If the first root
partition in the image is smaller, it will get resized too, including
the filesystem it contains.

Remove the old systemd-autoformat service and the mkfs-ext4 udev rule,
which also only handled the case where the data partition was the third
partition on the disk (which is not always the case anymore since we
have partitions for barebox-state or device-specific firmware).

[DistroKit] [PATCH v2 06/10] datapartition: add missing mount unit

[Roland Hieber]

The data partition has not been mounted since /etc/fstab was removed in
commit 5eb165a3722013d2c80d (2016-08-18, "ptxdist: version bump
2016.07.0 -> 2016.08.0"). Create the mount point, and add a systemd
mount unit based on the /dev/disk/by-usage/data symlink set up by our
custom rauc-udev rule.

[DistroKit] [PATCH v2 08/10] treewide: images: remove root-B and data partitions

[Roland Hieber]

These partitions are now generated on the first boot by systemd-repart.
The second rootfs is not needed for booting, and overwritten by RAUC
when a bundle is installed, so it can as well be empty. Remove the two
partitions to save space in the generated images.

[DistroKit] [PATCH v2 09/10] rauc-udev: generate symlinks based on GPT partition labels

[Roland Hieber]

Now that all our images have a GPT header which contains partitions
with the labels "root-A", "root-B", and "data", we can use those to
generate the symlinks in /dev/disk/by-usage/ instead of using the
hardcoded, number-based kernel device names. This gives us the
flexibility to change the order of the partitions on disk as long as
their GPT partition labels stay the same.

Since the symlinks in /dev/disk/by-partlabel/ are not necessarily unique
(see [1]), we cannot use these here. Instead, rework the current match
clauses to determine the devpath of the boot device based on the board
compatible, and only create by-usage symlinks for partitions on the boot
device.

[DistroKit] [PATCH v2 10/10] v7a: barebox: bootchooser: use GPT partition labels

[Roland Hieber]

Now that every image is in GPT format, we can use the devnodes that
include the partition label instead of the partition number to boot our
rootfs. These names are more readable and also more robust against
changing the order of the partitions. Make the change on all bareboxes
that didn't have that yet.

Use 'ignore' here. The license is for the source of the package and this
package has none.

For some reason this is breaking on some platforms in a way which I
didn't encounter during development, leading to a failed boot ending in
a rescue shell, with systemd-repart showing error message like:

  Can't fit requested partitions into available free space (768.0K), refusing.
  Automatically determined minimal disk image size as 604.2M, current image size is 14.7G.

…on a mmcblk0 of 14.7 GiB which only has 85 MiB of partitioned space… 🤔

I'll look into that, looks like I have to tickle systemd-repart to be a
bit more verbose about what it is trying to match.
