I have no ideas why these new issues. The only hint is the following

On container, one dbus session running:
% myps dbus
dbus 35 1 0 22:52 ? 00:00:00 /usr/bin/dbus-daemon
--system --address=systemd: --nofork --nopidfile --systemd-activation
--syslog-only
When on container I have 4 (when only 3 before). The one from vu-poppy
user (container) is new.
% myps dbus

I build my kernel with CONFIG_USER_NS=y since a while. I guess it is
this setting which cause the following trouble with UID/GID
From host
root@hortensia ➤➤ ~aur # ls -al $POPPY/var/log/journal
total 0
drwxr-xr-x+ 1 vu-poppy-0 systemd-journal 64 Oct 4 2016 ./
drwxr-xr-x 1 vu-poppy-0 vg-poppy-0 1.3K Jul 12 20:20 ../
drwxr-sr-x+ 1 root systemd-journal 7.8K Mar 11 15:25
59b720b533834a4eafe07a62c2482266/
From container:
root@thetradinghall ➤➤ dovecot/conf.d # ls -al /var/log/journal
total 0
drwxr-xr-x+ 1 root nobody 64 Oct 4 2016 ./
drwxr-xr-x 1 root root 1.3K Jul 12 20:20 ../
drwxr-sr-x+ 1 nobody nobody 7.8K Mar 11 15:25
59b720b533834a4eafe07a62c2482266/
As you can see, on host, root:root is by default vu-poppy-0 vg-poppy-0
On container, I am left with lots of files/folders owned by nobody.
---------------------------
When looking at the output of systemctl --failed, and verifying status,
I can observe a commun failure, like the one below:
postgresql.service: Failed at step KEYRING spawning
/usr/libexec/postgresql-check-db-dir: Permission denied
-----------------------------
When upgrading some package, I have again a permission issue.
# dnf upgrade filesystem
......................
error: unpacking of archive failed on file /proc: cpio: chown
# ls -al /proc/filesystems
.........
-r--r--r-- 1 nobody nobody 0 Jul 13 14:22 /proc/filesystems
.....................
# chown root:root /proc/filesystems
chown: changing ownership of '/proc/filesystems': Operation not permitted
-------------------------------------
Can anyone help me in debugging my system, as it starts to be difficult
to use the container. Thank you
