This is a security release featuring latest version of Flatcar Container Linux.

Change details

containerlinux 3815.2.2

Changes since Stable 3815.2.1

Security fixes:

Bug fixes:

  • Disabled user-configdrive.service on OpenStack when config drive is used, which caused the hostname to be overwritten. The coreos-cloudinit.service unit already runs on OpenStack if the system is not configured via ignition. (Flatcar#1385)
  • Fixed toolbox to prevent mounted ctr snapshots from being garbage-collected (toolbox#9)

Changes:

  • Disabled real-time priority for multipathd as it prevents the cgroups2 cpu controller from working. (scripts#1771)
  • SDK: Unified qemu image formats, so that the qemu_uefi build target provides the regular qemu and the qemu_uefi_secure artifacts (scripts#1847)
