I think have have most, if not all, animals with lz4 packages installed
with lz4 now. (I've been trying to use Ansible to help, but there are
still a number of systems Ansible isn't able to help me with.)

What feels like the best way to continue at this point? Does having me
update configs to set --with-lz4 make more sense than changing the
default?
