Hi Robie,
In terms of gawk being included by default on certain Ubuntu installs, this
is a bug to be aware of that can impact upgrades:
https://bugs.debian.org/932752
I think I've looked at the byobu gawk dependency at least once before and
unfortunately the awk usage in /usr/bin/byobu-select-profile is not
compatible with mawk per
<https://bugs.launchpad.net/ubuntu/+source/byobu/+bug/1166416>.
