strace for first issue
I updated to systemd 211 (which should have the fix for <a class="bz_bug_link
bz_status_RESOLVED bz_closed"
title="RESOLVED FIXED - systemd-nspawn: run command as user in i686 container on x86_64 OS fails"
href="show_bug.cgi?id=75733">bug 75733</a>, if I'm not
mistaken) from rawhide on my base Fedora 20 x86_64 OS, then rebooted. I am now
having a few new issues when trying to run commands as a user in a 32-bit
(i686) container on an x86_64 host OS. These issues do not happen if the
container is a 64-bit (x86_64) container.
#### Issue 1 ####
Running systemd-nspawn with -u <user> option to execute a command when <user>
is part of the "wheel" group in the container.
$ uname -r
3.13.6-200.fc20.x86_64
$ su -
$ mkdir /srv/mycontainer-i686
$ mkdir -p /srv/mycontainer-i686/etc/yum/vars
$ echo i386 > /srv/mycontainer-i686/etc/yum/vars/basearch
$ echo i686 > /srv/mycontainer-i686/etc/yum/vars/arch
$ yum -y --releasever=20 --nogpg --installroot=/srv/mycontainer-i686
--disablerepo='*' --enablerepo=fedora install systemd passwd yum fedora-release
vim-minimal sudo
$ systemd-nspawn -D /srv/mycontainer-i686 adduser jail
$ systemd-nspawn -D /srv/mycontainer-i686 passwd -d jail
$ systemd-nspawn -u jail -D /srv/mycontainer-i686 whoami
Spawning container mycontainer-i686 on /srv/mycontainer-i686. Press ^] three
times within 1s to abort execution.

$ systemd-nspawn -u jail -D /srv/mycontainer-i686 whoami
Spawning container mycontainer-i686 on /srv/mycontainer-i686. Press ^] three
times within 1s to abort execution.
Out of memory.
Container mycontainer-i686 failed with error code 1.
#### Issue 2 ####
Running systemd-nspawn as root to execute an "su <user> -c <command>" command.
$ uname -r

$ su -

$ echo i686 > /srv/mycontainer-i686/etc/yum/vars/arch
$ yum -y --releasever=20 --nogpg --installroot=/srv/mycontainer-i686
--disablerepo='*' --enablerepo=fedora install systemd passwd yum fedora-release
vim-minimal sudo

su: System error

I've attached straces for both of the issues if that helps.</pre>
