Config Cgroup2 without the /etc/fstab

I want to load Podman and configure Cgroup2 to mount during bootup.
How is it possible to do this without /etc/fstab ???

swupd bundle-add containers-basic

if no system dir there yet, create it
mkdir -p /etc/systemd/system

create new file
nano /etc/systemd/system/cgroup2.mount

add this to the new file :

[Unit]
Description=Mount cgroup2 filesystem
DefaultDependencies=no
Before=local-fs.target

[Mount]
What=cgroup2
Where=/sys/fs/cgroup
Type=cgroup2
Options=nsdelegate

[Install]
WantedBy=multi-user.target

save and close the file

systemctl daemon-reload

systemctl enable cgroup2.mount


Config Podman

mkdir -p /etc/containers

create new config file
nano /etc/containers/containers.conf

add this

[cgroup_manager]
cgroup_manager = "systemd"

[engine]
cgroup_manager = "systemd"
events_logger = "journald"

Create a new systemd service file
sudo nano /etc/systemd/system/podman.service

add this

[Unit]
Description=Podman API Service
Requires=cgroup2.mount
After=cgroup2.mount

[Service]
Type=simple
ExecStart=/usr/bin/podman system service

[Install]
WantedBy=multi-user.target

Save and close the file

systemctl daemon-reload

systemctl enable podman.service

reboot
