    configs/cgroup: Make cgroup v1 the default hierarcy
    
    Add "systemd.unified_cgroup_hierarchy=0" to the kernel boot command line
    which effectively asks kernel to use cgroups v1 by default.
    
    If someone wants to use cgroups v2, adding
    systemd.unified_cgroup_hierarchy=1 into the grub kernel command line
    will do the trick.
