Till something different happens with the linux licensing model, I'm not 
convinced that it will ever "officially" have ZFS.   Reviewing the


web site, ZFS is still an add-on item.  Looks like the last code release was on 
13 October 2015.  Pretty recent.

I don't know that this was ever resolved from a general OS perspective. 
Supporting "highly" memory hungry applications, I'm still manually holding back 
the ARC (in /etc/system) from grabbing everything on boot.

If you look at the docs and code for the OpenSolaris ARM port, there is a 
special version of ZFS, called CZFS, for usage in low memory/embedded devices.

*BSD - Probably a "master of the obvious" statement, but in my experience, *BSD 
releases have always excelled in my observation in the ability to slim down and 
fly on small, light-weight, old hardware.  At least vs. any other x86 Unix or 
Unix-clone I have worked with.
