[cfarm-users] Nvidia Jetson AGX Xavier in beta access (gcc80)

Even though individual users can fix it in their personal rc file, it
would be arguably appropriate to comment all LC_* assignments in
/etc/default/locale. And while at it, one can even argue that
LANG=C.UTF-8 would be more neutral choice;-)

As for GPU programming. On Jetson by default only members of 'video'
group can execute CUDA programs, and members of 'debug' group can debug.
So that *if* you [still] want to provide general access to GPU you'd
need to either make everybody member of these group, or arrange
universal access to relevant /dev/nv* entries. One way to achieve the
latter is to comment corresponding lines in
/etc/udev/rules.d/99-tegra-devices.rules.

[Just in case for reference. "On Jetson by default" means that on x86_64
default is different and it's "everybody can run CUDA." Also for
reference. On x86_64 /dev/nvram is accessible only by root, which ought
to mean that it's not given that one has to comment *all* nv* entries in
/etc/udev/rules.d/99-tegra-devices.rules, some experimentation would be
required.]

Cheers.
