We can create a completely repeatable portable mechanism to distribute 
applications with full dependency chains as part of the distribution, 
across machines of any linux distro type, without impact core packages 
(which in the case of specific distros are often non-functional for 
anything but legacy system work) ... and you don't see the benefit to this?


Quick show of hands:  Anyone running an HPC system, ever run into, say, 
a dependency hell/nightmare due to a package requirement?

Response in the olden days was "tough we won't support it", and you had 
to figure out how to do it on your own (I did this with a number of 
packages on Cray's in the early 90's at PSC, that my group needed).  Or 
you package up what you need in a docker container, and run it, anywhere.
