==== Linux security modules

===== SELinux
TODO get hello world working.
....
./build-linux \
--config-fragment linux_config/selinux \
--linux-build-id selinux \
;
....
But then this fails currently:
....
./build-buildroot --config 'BR2_PACKAGE_SETOOLS=y'
....
because we use ucLibc which is incompatible with SELinux, with a trivial unmerged fix at: http://lists.busybox.net/pipermail/buildroot/2017-July/197793.html
=== User mode Linux
I once got link:https://en.wikipedia.org/wiki/User-mode_Linux[UML] running on a minimal Buildroot setup at: https://unix.stackexchange.com/questions/73203/how-to-create-rootfs-for-user-mode-linux-on-fedora-18/372207#372207
