Hey out there.

     I've got a Pi-Top a few months ago and leaved it on a shelf for a 
while. Around a dozen days ago they released a new version of their 
PiOS, codenamed "jessie", and, guess what: it's all infected with Systemd.

     I found a website still offering a Raspbian-wheezy image for 
download, downloaded it, changed the partitionning to make some room to 
/var for apt's cache, then followed the procedure of dev1fanboy.

     It worked very well and I now have Devuan installed on my Pi-Top, 
which is a Raspberry-Pi B2.I just found three errors in one line of 
dev1faboy's howto:

root@debian:~# apt-get upudate && install devuan-keyring -y

     1) a typo: "apt-get upudate", should be "apt-get update"
     2) a typo: missing apt-get after &&
     3) -y doesn't do it, the package not being signed requires 
--force-yes in that case, or just removing the -y and answering y 
interactively.

BTW, dev1fanboy, I sent you french translations of two of your documents
a few days ago, but you didn't reply, therefore I guess my mail was
treated as spam or lost in some other way.
