[DistroKit] [PATCH next v3 0/4] refactor data partition setup

[DistroKit] [PATCH next v3 0/4] refactor data partition setup

[Roland Hieber]

PATCH next v3:
* fixups to make the state of the series already applied on the next
  branch work on remaining platforms
* don't use "linux-generic" Type UUID for data partition because then
  systemd-repart will match the STM32MP1 bootloader partitions
* select busybox rdev, and don't run systemd-repart when we don't have a
  partitionable disk (feedback from PTX Jenkins, Bastian Krause and
  Robert Schwebel)
* fix systemd-repart on mips (feedback from PTX Jenkins)
* rauc-udev: remove fallback match for data partition in mmcblk0p3

PATCH v2: https://lore.distrokit.org/distrokit/20231103225253.1349209-1-rhi@pengutronix.de
* 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

Roland Hieber (4):
  systemd: make systemd-repart work for mips
  busybox: enable rdev to find out the root device
  squash! datapartition: generate partitions via systemd-repart
  fixup! rauc-udev: generate symlinks based on GPT partition labels

[DistroKit] [PATCH next v3 1/4] systemd: make systemd-repart work for mips

[Roland Hieber]

systemd v254 doesn't know about the partition type GUID for big-endian
MIPS root partitions yet, so systemd-repart fails to parse the
"Type=root" setting in its config, and fails to start. Backport a patch
from systemd 255-rc1, which will wire up the respective GUID.

[DistroKit] [PATCH next v3 3/4] squash! datapartition: generate partitions via systemd-repart

[Roland Hieber]

[@rsc: please replace the last paragraph in the original commit
message by the following text:]

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), and
replace it with a call to systemd-repart if the root partition is on a
disk that we can actually repartition (i.e. /dev/root is not emulated
via qemu; this should also match the case when we are running from
initrd, but this has not been tested.)

Use a custom Type UUID instead of "linux-generic" for the data partition
to prevent systemd-repart from matching any bootloader partitions that
could throw off the matching algorithm (e.g. on STM32MP1).

[DistroKit] [PATCH next v3 4/4] fixup! rauc-udev: generate symlinks based on GPT partition labels

[Roland Hieber]

Signed-off-by: Roland Hieber <rhi@pengutronix.de>

The assumption made in the comment does not hold true, as the fallback
match for mmcblk0p3 conflicts with any possible match made later with
the 'boot_disk' tag a few lines below, so the probe order will influence
the actual target of the symlink and lead to unwanted consequences.
Since we removed the data partition from all genimage configs in a
previous commit ("treewide: images: remove root-B and data partitions"),
the fallback does not match anyway.

Re: [DistroKit] [PATCH next v3 0/4] refactor data partition setup

[Robert Schwebel]

Thx, the series is now integrated into next, and the CI results look
good.
