I'm still getting used to the mailing list so sorry if this starts a
second post

I didn't realise I would get such a good response for sharing a little
knowledge, thanks to everyone for the compliments and for resharing. I
posted here just hoping to help someone for now until I had more to
share. I wasn't sure how to respond at first as I'm not used to
publishing but I will say that yes I'm happy for everyone to share,
modify, and reuse my previous post/work on upgrading devuan and
configuring minimalism. Please also give others permission to do so,
and you can just mention dev1fanboy if you like.  

It was kindly suggested to me by one of the installer devs from the
debianfork channel that I could share it on the devuan gitlib instance
under my own project. I didn't realise they had it open for others to
sign up (which is cool), or maybe it's my noobishness about gitlab as
well but i have posted it here:

As people seem quite happy that I did publish, I will try to find time
to improving what's already there.
