[Hosting] Equipement donations and Inflow walk-through?

[John Turner]

Just do make things clear to me. You are building using the
tools and libraries from different distros, but the kernel
is always the host version/distro. This seems fine for all
but the most low level applications. Which we are unlikely
to be building or testing.
