Hi Dave,
thx for your perseverance :-)
I have (at least) one question for you before I attempt this:

showing my ignorance here: where do I get these .txz files?

should devfs be in /etc/fstab? in my current BE, it isn't ...
if so: do you have an example of such a line? In the instances I looked up,
I wasn't quite able to make it work (but perhaps that's a dead end anyway).
# bectl activate -t vanilla

Thx
