That's what I was thinking.  Having an easily removable disk and a 
having computer around with *much* more disk capacity make it a lot 
less critical than it used to be exactly how partitions are set up, 
because it's easy to copy everything off and on again.

Are there considerations against lvm that are specific to raspberry pi 
or microsd cards?  I dont know of any, but there are a lot of things I 
don't know.

Considering that all I've done so far is install by dd'ing from a file 
on my laptop, I still have all the pieces correctly assembled 
elsewhere.  Now if the time to fuck up, if I'm going to

Thanks for the report. The history function only keeps track of pkgs 
installed via synaptic not those installed from terminal so it is 
incomplete if you use both methods. There have been times that history 
has come in very handy!  It is fine in Jessie but there have been a few 
annoyances in ascii.  The one addressed in this email was self-inflicted 
by neutering the entire adwaita icon theme. Now only the cursor 
directory is disabled so everything else is working properly.

I started with the devuan raspi3 image under devuan_jessie/embedded
on http://files.devuan.org.  The machine is a raspbrry pi 3B.

Turns out I dont know where to go from here.  Yes, use apt-get to 
install what I want.  But apt-get needs a network connection.

As a temporary measure I can use a wired connection, but my ethernet 
switches have disappeared during the move to my new apartment, and as a 
result I have to shut off wifi whenever I do this.   The rest of the 
family complains.

So what tools are there in the minimal installed raspberry pi devuan 
jessie to activate wifi?

Even with lxde installed, its network manager tool doesn't seem to be 
able to find wifi -- presumably some infrastructure is missing.

man -k wifi didn't help.  Presumably there's no relevant package 
installed.  If it were it would probably be working and I wouldn't be 
looking for it.

Not removed.  Renamed that directory to

..setnet.sh? AKA setnet:

ii setnet 0.3.2+devuan1.2 all simple shell/dialog tool to configure
   networks

..ugh, I hear you, and I was lucky with my rpi1Bv1s and came here 
to devuan because of Debian SystemD ways of messing up wifi ETC on 
my laptops, so I'm not much help here, unless setnet.sh helps you.

..tried sticking in your old Raspian card and running "dpkg \
--get-selections >gotten-selections-$(date +%F+%T+%Z) "?

..allows e.g. "cat gotten-selections-2018-01-25+01:04:08+CET \
|dpkg --set-selections ", details in "dpkg --help".

..and "dpkg -l |less " is a little less terse than "dpkg \
--get-selections ".

..pass, haven't used it in years.


.._one_ way to make your own history, is e.g. run "dpkg \ 
--get-selections >gotten-selections-$(date +%F+%T+%Z) \
&&aptitude||synaptic ||apt-get ||apt-program-du-jour \
&&dpkg --get-selections >gotten-selections-$(date +%F+%T+%Z) " 
and diff those gotten-selections-* files against each other.


..allows e.g. "cat gotten-selections-2018-01-25+01:04:08+CET \
|dpkg --set-selections " if you mess up something, details in 
"dpkg --help".


.."dpkg -l " is a little less terse than "dpkg --get-selections ",
adding version numbers, architecture and a terse description. ;o)
