At the same time as you're submitting this, I'm seriously considering a
change where instead of noexec, we'd deltask these tasks. The reason
being I'm not very keen on subverting the package manager and I'm not
convinced this is a particularly desirable way to be altering the
rootfs.

Except this isn't an sstate task? There is no setscene task variant of
the main task. There are no sstate variables set either...
