Makes sense when you spell it out :)

Either one looks fine. Maybe let's use Debian so that we don't put
all eggs in RPM-based baskets ;)

Unfortunately he bubble is simply too small to display a reasonable
amount of information, so I don't think we can hope to fit everything
in there. The "jobs" view presents all information, but its structure
is less than ideal.

Recently Cleber created this script for QEMU:

  https://lists.nongnu.org/archive/html/qemu-devel/2020-07/msg03106.html

I wonder if we could build something like that, but which provides
more detailed information, perhaps in a proper TUI... Such a tool
might live under the Bichon umbrella, for example, since there's
clearly some overlap in scope.
