To limit to 20% of 1 CPU
$ podman run --cpu-quota=20000 <IMAGE> # shares of --cpu-period, default 100000
$ systemd-run --user --scope -u your-scope-name.scope -p CPUQuota='20%' <CMD>

Manually:
1) create a directory (new cgroup) in /sys/fs/cgroup 
  - ideally under some existing cgroup if applicable
  - directory might differ: see `mount|grep cgroup2` - you can mount it by yourself if it's missing
2) write "cpu" to underlying cgroup.controllers (all higher cgroups must have that as well)
3) write "20000 100000" into cpu.max (it's share and granularity)

# some useful notes
# - -F does not work in compgen, so does many of -o args
# - docs about competion: `info bash`, last three chapters of "Command Line Editing"
# - bash-completions helpers are not very well documented
# - -G is useless, somehow it does not trigger filling the command line, use -A file -X "!<glob>"
