Serge: > Will it use the same name every time? Will it eventually go away?
I don’t' know but I expect it will get some ID which represents the file reference on the NFS server. And it "disappear" (, i.e. it will be deleted in the normal way), if the filehandle is closed. Other NFS clients will see this "hidden" file and I expect that they even may open it. This emulation of unlink by a rename try to simulate the stateful behavior of a local file system.

Good point. If it will hold open while a container is running, then it's a "left-over", if lxc-start detect another ones handle on it. But a file content might be more easy to handle by all kind of other programing languages that may take use of this file and will also work reliable on a shared file system. Therefore, if something like the PID is written to the file, please also add the hostname, e.g. <pid>@<hostname> ------------------------------------------------------------------------------ LIMITED TIME SALE - Full Year of Microsoft Training For Just $49.99! 1,500+ hours of tutorials including VisualStudio 2012, Windows 8, SharePoint 2013, SQL 2012, MVC 4, more.
