To be frank, grsecurity support in NixOS is user-unfriendly. My biggest
gripe is that the implementation is biased towards compile-time tuning
of run-time behavior. I proposed a few patches towards a sysctl oriented
implementation, but they failed to gain traction (granted, the patches
are imperfect and incomplete). What is more, the lack of a satisfying
method of applying appropriate PaX flags to binaries, ala paxd, greatly
impedes use of Grsecurity/PaX on the desktop. Finally, I failed to get
RBAC to actually work, in its current form.

I have found it easier to simply switch to a distro with proper
Grsecurity/PaX support. If I continue to tinker with NixOS, it will be
in a virtual machine.

Just my 2 NOK ...
