Bug#916689: systemd: login at console hangs after "Last login..." displayed, ssh hangs as well

[Raphael Manfredi]

Quoting Michael Biebl:
: Please boot with systemd as PID 1 and try to get a debug shell on tty9
: by adding systemd.debug-shell=1 to the kernel command line.
: 
: On tty9 you can then inspect the system.
: The output of
: systemctl status dbus
: systemctl status systemd-logind
: systemctl list-jobs
: would be a good start.

It booted but...

	/etc/profile puts /usr/local/bin at the start of the PATH.

This created problems: for some reason, the autofs mount of /usr/local
was not working.  I changed /etc/profile to remove these /usr/local
prepending.  I also reset the PATH at the command line to avoid
/usr/local....

(This is funny. Autofs was started, see mount output below, but indeed
trying to access any of the auto-mounted dirs failed -- I forgot to
test my network by issuing a ping).

Next, a basic ps -ef worked and showed /sbin/init as being PID 1.
It's a symlink:
		lrwxrwxrwx 1 root root 20 Oct 28 18:02 /sbin/init -> /lib/systemd/systemd

So I was under systemd.

I launched these commands (typing the full path just in case):

	# /bin/systemctl status dbus
	# /bin/systemctl status systemd-logingd
	# /bin/systemctl list-jobs

All three hung and I had to ^C them after a few secs.

: A verbose debug log would be helpful as well.

Tell me what log you want.  The output of "dmesg"?  Some other log file?

I captured the output of mount:
