The only place that's being used is in creating a symlink... /dev/.lxc/$name -> /dev/.lxc/$pathhash I use it for the same reason you wanted the extra bind mounts to $lxcpath/$lxcname.dev. In your case, you wanted to see the dev mappings in the mount tables, in my case I was going for them in the symlinks in /dev/. It's so I can correlate a cgroup name and browsing the cgroups with the same name in /dev/.lxc. > > Is that something I should be pulling out of the > > cgroup info structure? > Yes. I don't know offhand where though. K I'll look into that deeper. Right now I'm going to play with this whole idea of two containers with the same name and see how all that works. I'm also trying to figure out where those "rootfsproc" and "rootfssys" subdirectories in /var/lib/lxc/$name/ are being creating. I'm having a hard time pinning them down in the source and I want to do something similar for rootfsdev. > -serge Regards, Mike -- Michael H.
