# Pastebin mlAOGSGg
Started as user zyga from the terminal in gnome shell session on Fedora 31, using the run-in-scope helper produced below:

0) the helper run-in-scope, used for non-service workloads:
#!/bin/sh -e
busctl $(test $(id -u) -eq 0 || echo --user) call org.freedesktop.systemd1 /org/freedesktop/systemd1 org.freedesktop.systemd1.Manager StartTransientUnit 'ssa(sv)a(sa(sv))' testing.$(cat /proc/sys/kernel/random/uuid).scope fail 1 PIDs au 1 $BASHPID 0
exec "$@"

1) moving bash running in gnome-terminal to a scope:

[zyga@fedora31 ~]$ time busctl --user call org.freedesktop.systemd1 /org/freedesktop/systemd1 org.freedesktop.systemd1.Manager StartTransientUnit 'ssa(sv)a(sa(sv))' testing.$(cat /proc/sys/kernel/random/uuid).scope fail 1 PIDs au 1 $BASHPID 0

[zyga@fedora31 ~]$ cat /proc/self/cgroup 
0::/user.slice/user-1000.slice/user@1000.service/testing.cd8f04c3-56d2-425a-a74a-0693440a78a3.scope

[zyga@fedora31 ~]$ ls -ld /sys/fs/cgroup/user.slice/user-1000.slice/user@1000.service/testing.cd8f04c3-56d2-425a-a74a-0693440a78a3.scope
drwxr-xr-x. 2 zyga zyga 0 11-07 17:01 /sys/fs/cgroup/user.slice/user-1000.slice/user@1000.service/testing.cd8f04c3-56d2-425a-a74a-0693440a78a3.scope

2) starting firefox from the terminal via run-in-scope

[zyga@fedora31 ~]$ run-in-scope firefox
o "/org/freedesktop/systemd1/job/749"

[zyga@fedora31 ~]$ pgrep firefox
4416

[zyga@fedora31 ~]$ cat /proc/4416/cgroup 
0::/user.slice/user-1000.slice/user@1000.service/testing.724938bf-1d80-4f85-826c-eafb20f773c4.scope

[zyga@fedora31 ~]$ ls -ld /sys/fs/cgroup//user.slice/user-1000.slice/user@1000.service/testing.724938bf-1d80-4f85-826c-eafb20f773c4.scope
drwxr-xr-x. 2 zyga zyga 0 11-07 17:10 /sys/fs/cgroup//user.slice/user-1000.slice/user@1000.service/testing.724938bf-1d80-4f85-826c-eafb20f773c4.scope

3) starting a service without run-in-scope

[zyga@fedora31 ~]$ sudo systemctl start sleep.service
[zyga@fedora31 ~]$ systemctl status sleep.service
● sleep.service
   Loaded: loaded (/etc/systemd/system/sleep.service; disabled; vendor preset: >
   Active: active (running) since Thu 2019-11-07 17:15:02 CET; 2s ago

[zyga@fedora31 ~]$ cat /proc/4933/cgroup

[zyga@fedora31 ~]$ ls -ld /sys/fs/cgroup//system.slice/sleep.service
drwxr-xr-x. 2 root root 0 11-07 17:15 /sys/fs/cgroup//system.slice/sleep.service

4) service using run-in-scope

[zyga@fedora31 ~]$ systemctl status sleep.service
● sleep.service
   Loaded: loaded (/etc/systemd/system/sleep.service; disabled; vendor preset: >
   Active: active (running) since Thu 2019-11-07 17:30:40 CET; 2s ago
 Main PID: 5723 (sleep)
    Tasks: 0 (limit: 9477)
   Memory: 752.0K
      CPU: 9ms
   CGroup: /system.slice/sleep.service
           ‣ 5723 /usr/bin/sleep 1h


[zyga@fedora31 ~]$ cat /proc/5723/cgroup 
0::/system.slice/testing.fff74326-e5c4-433e-b105-af74b2dad09b.scope

NOTE: Did systemd steal a service from itself? There's a discrepancy between systemctl status and proc/[pid]/cgroup.
