I'm building Docker containers using an executable installer that is not very configurable. It wants to install about 9GB of modules in various folders around the system, of which I actually need to keep about 500MB. Instead of waiting for the installer to write to all of these files, then deleting the ones I don't need, it would be nice to be able to fake writes to these directories, where instead of actually doing disk I/O, these writes just disappear into the ether.
Is there a way to set up a folder that will not persist any files written to it and doesn't require waiting for disk I/O when writing?
