@Serge,
Could you explain why use of --path can lead to X crashing where lxc-create
without --path is not?
My motivation was: I don't want lxc-create to create the rootfs under
/var/lib/lxc.
I need the stuff to be stored elsewhere.
I thought that the --path option in the template was made
Confirmed: running the same lxc-create command with --trim creates a
directly usable container.

After creating such a container, look at /var/lib/lxc/container/config
and provided-path/config.

@Michael (and @Steve)
So plymouth must do stuff over netlink. Instead of using --trim, you
can simply add the lines from /etc/lxc/lxc.conf to the config file in
your custom path. By not having those lines, you are telling lxc not to
create a new network namespace. That means the container is
Sorry, I said netlink, but a unix socket is more likely. same root

@Serge,
thanks for your comments.
I have experimented a little more. And I found that --path is indead at
the very least misleading:
If I don't use --path, then the config (snippet) given to lxc-create by
-f is merged with the config that the template creates. If i do use
paht, then the -f file
@Steve,
regarding whether disabling plymouth is the right fix: I don't know the
mechanisms plymouth uses.
1. for system log entries, the right fix will be a syslog namespace,
which doesn't yet exist.
2. if it uses proc files, we may be able to use apparmor to protect from
plymouth, though that
@Serge,
I might have misready your statement about network config.
I do add nettwork config (veth0, dev=virbr0, etc) manually.
There is no /etc/lxc/lxc.conf in my system.
The reason I used a config file snipped for lxc-create was
exactly to get this network virtualization layer into the container

What do you mean by adding it manually? Have you added it to the

Does it write it straight to /var/log/boot.log, or does it do it through
syslog(2) or syslog(3)? If it writes straight to /var/log/boot.log then
there should be no problem.
Yes, it's straight to the log file.
/dev/console and /dev/tty{1-4} are bind-mounted pty devices, and are ok

Hi,
plymouth running in the container prevents me from using
the container at all, it kills my X instead:
I created a 11.10 container with the following lxc-create command on
freshly installed 11.10:
sudo lxc-create -n ubuntu1 -f ./ubuntu1-template.conf -t ubuntu --
--release=oneiric
I understand how plymouth currently running in the container might cause
problems. My doubt is that disabling plymouth in the container is the
right fix.

@Michael,
your problem with X crashing is actually due to your using the '--path'
option. Please don't use that. It is only meant to be specified by
lxc-create to the template. We've specifically removed --path from the
help output because it does the wrong thing when used by hand and is
I'm having trouble sussing out the underlying principle here that
warrants special-casing plymouth in a container. Plymouth is the
standard boot-time I/O multiplexer; any upstart jobs that need to
interact with the user at boot time should be using plymouth. Now for
the most part, this currently
