It's obviously not what you're thinking of, but there's Singularity, under review <https://bugzilla.redhat.com/show_bug.cgi?id=1331818>. As an example, I haven't managed to port Scilab packaging to EPEL6, but with singularity I can run the f23 version (or the Debian one) on RHEL6: $ scilab -version Scilab version "5.5.2.1427793548" scilab-5.5.2 The executable is basically a Fedora 23 system image (installed with yum, and quite large) with a configured entry point, in which you can run other commands: $ singularity exec `which scilab` rpm -q basesystem basesystem-11-1.fc23.noarch I'm not sure about "both ways", but you can operate on the contents as appropriate. > In my mind, containers are primarily useful to run arbitrary untrusted > third party applications, but of course they need a good enough > sandbox system for that.

That's the job of the HPC resource manager, if anything. -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://lists.fedoraproject.org/admin/lists/devel@xxxxxxxxxxxxxxxxxxxxxxx
