I like this series!

Speaking of devshell, last I tried (and Paul E can correct me here)
Konsole doesn't wait when it's spawned so is currently pretty useless
for devshell (bitbake continues as if the devshell had finished and if a
patch hasn't applied....).

Perhaps we should remove support for it from the class? Or is there some
better way we can work around this?

As an aside: I think somewhere in meta-yocto, to maintain current
behaviour we'd want to set: OE_TERMINAL ?= 'Gnome' to maintain
gnome-terminal as the default (when installed).

Cheers,
