[Lxc-users] Mounting filesystem for container

Well, yes, that fixed it. Thank you. 

I had a gap in my knowledge. I assumed incorrectly that the mount was
handled in the Host Environment and that the container would just see the
mounted file system, therefore not needing access to the file systems's
device node. 

However, I now see that is not the case - the mount is performed within the
container and is not actually visible in the host environment (actually a
good thing!). This leads me to ask some more questions though...

1) Why not just put the mount inside the container's /etc/fstab ?

2) When do these mounts happen? I have a problem with a daemon not starting
during boot because, I think, the filesystem it needs is not yet there.

sorry, just learning this stuff - very keen to leave OpenVZ behind -:)

John.
