# Enabling cgroups for Raspbian Buster
Standard Raspbian Buster installations do not start with `cgroups` enabled. **K3S** needs `cgroups` to start the systemd service. `cgroups`can be enabled by appending `cgroup_memory=1 cgroup_enable=memory` to `/boot/cmdline.txt`.
## example of /boot/cmdline.txt
```
console=serial0,115200 console=tty1 root=PARTUUID=58b06195-02 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait cgroup_memory=1 cgroup_enable=memory
```
# SELinux Support
_Supported as of v1.19.4+k3s1. Experimental as of v1.17.4+k3s1._
