http://www.ni.com/linux/ for some helpful info.

While the 2015 roboRIO does run linux, it uses the opkg package manager from OpenWRT and some package repositories from Ångström, calling it Ångström Linux would not be correct. Notice that the NI link never mentions Ångström. Calling in NI Linux Real-Time is correct, as your link points out. Depending on what you want to do, playing with a kernel with the PREEMPT_RT patch could be more valuable, or playing with Java SE Embedded.
