I'd like to play with LXC but I find the docs not very newbie-

I'm trying to follow a guide at:
https://brandonrozek.com/blog/lxc-fedora-38/
(basically because it mentions Fedora). I followed the steps closely
and rebooted, but I get the following error:
$ systemd-run --unit=my-unit --user --scope -p "Delegate=yes" --
lxc-start test
Running scope as unit: my-unit.scope
lxc-start: test: lxccontainer.c: wait_on_daemonized_start: 877
Received container state "ABORTING" instead of "RUNNING"
lxc-start: test: tools/lxc_start.c: main: 306 The container failed
to start
lxc-start: test: tools/lxc_start.c: main: 309 To get more details,
run the container in foreground mode
lxc-start: test: tools/lxc_start.c: main: 311 Additional
information can be obtained by setting the --logfile and --
logpriority options
Any insights would be welcome. (Just in case, I tried running with
SElinux turned off, but it made no difference.)
One thing: on running lxc-checkconfig I get:
...
Cgroup v1 systemd controller: missing
Cgroup v1 freezer controller: missing
Cgroup ns_cgroup: required
...
(everything else is OK).
The first two are irrelevant. It uses cgroup2 now. 3rd one I don't
understand.
How is your test container working?
I've been playing along over here and now have a container that reports
"UNPRIVILEGED true" using lxc-ls -f. It starts and runs but is
unusable. lxc-start -n C1 -F shows the bootup sequence and it is full
of [FAILED] sections. root can't even change to /root: permission
denied. Almost everything is owned by 65534:65534. If I manually set
an IP and default route I have networking and it uses my DNS container
successfully.
I found this: https://brandonrozek.com/blog/lxc-fedora-38/ "Setting up
unprivileged containers with LXC on Fedora 38" and how to use systemd to
start and stop the containers. It works but doesn't solve the other
problems I'm seeing.
