  • Workaround for the error in determining the RAID device in use.
  • Added another mechanism for determining dependencies in raid devices.

• Feature guess-nvme:

  • The feature adds the ability to search and add nvme devices.

• Feature fsck:

  • Add fsck arguments support by @Vedingrot.

Full Changelog: 2.55.2...2.56.0

Changes

• Feature add-modules:

  • Make crc32-generic optional.
  • Implicit dependencies should not be mandatory.

• Feature modules-virtio:

  • Fix symbol filter to support new kernels.

• Feature pipeline:

  • Allow to mount latest version of image.

• Feature runtime:

  • Create a necessary core device files (/dev/null, /dev/zero, etc.) if it is necessary.

• Guess device-tree:

  • Fix typo in the variable name "modalias".

Full Changelog: 2.55.1...2.55.2

Changes

• Feature fsck:

  • Split fsck arguments. fsck.f2fs enters an infinite loop with the combination of arguments -py, but if separated into -p and -y, it works normally.

• Feature plymouth:

  • Fix syntax error in rules.mk.

• Misc:

  • Improved performance of string quoting for splitting it into separate arguments without executing any possible shell code in it.

Full Changelog: 2.55.0...2.55.1

Changes

  • Hide losetup from busybox. This allows other implementations of losetup to be used.
  • Allow to pack filename with spaces.
  • Replace gen_init_cpio by cpio.
  • Split output into levels.
  • Avoid copying files to temporary root.
  • Include features/*/rules.mk only once.

• Feature system-glibc:

  • Do not remove the root password if it exists.

  • Use own utility to switch root.

• Feature runtime-compressed-fs:

  • This feature introduces support for building a compressed initramfs
    to significantly reduce memory usage during system boot.

• Guess device-tree:

  • This feature scans the device tree [1] for compatible nodes and
    determines which kernel modules are required for the current
    hardware.

• Guess loaded-modules:

  • Drop this guess feature. This feature was needed as a workaround to
    the problem of not being able to parse Device Tree (DT).

    core files are no different from the data in the features.

• Guess:

  • Add the ability to add optional modules.

• Guess loaded-modules:

  • Add more directories with kernel modules.
  • Consider modules as optional. Modules that feature adds may not be
