[lxc-users] lxc-start-ephemeral: --storage-type dir leaves data behind

[juodumas]

Hello,

1. Shouldn't ephemeral containers delete data after they are stopped? Data is
   left behind when I use the '--storage-type dir' argument.
2. How do I delete leftover data with my unprivileged user after stopping the
   ephemeral container?

Here is an example session on Ubuntu 14.04:

[1]$ ls -l ~/.local/share/lxc/
drwxrwx--- 3  100000 ubuntu 4096 Feb 12 10:59 ubuntu-trusty

[2]$ lxc-start-ephemeral -o ubuntu-trusty -n ephemeral -s dir -- pwd
/root

[3]$ ls -l ~/.local/share/lxc/
drwxrwx--- 3  100000 ubuntu 4096 Feb 12 10:59 ubuntu-trusty
drwxrwxr-x 3  100000 ubuntu 4096 Feb 12 23:12 ephemeral

[4]$ lxc-usernsexec -- rm -fr ~/.local/share/lxc/ephemeral/
rm: cannot remove ‘/home/ubuntu/.local/share/lxc/ephemeral/’: Permission denied

[5]$ rmdir ~/.local/share/lxc/ephemeral

So it looks like I can delete the leftover data in 2 steps: [4] and [5].
Is this the right way to do it? Can this cleanup be done with a single
command? Shouldn't this be handled by the lxc-start-ephemeral script?
