In 256 support for cgroup v1 ('legacy' and 'hybrid' hierarchies) is now considered obsolete and systemd by default will refuse to boot under it.
|
||
To forcibly reenable cgroup v1 support, you can set boot.kernelParams = [ "systemd.unified_cgroup_hierachy=0" "SYSTEMD_CGROUP_ENABLE_LEGACY_FORCE=1" ].
|
||
NixOS does not officially support this configuration and might cause your system to be unbootable in future versions. You are on your own.
