There are two ways to have Devuan run on your computer:
1) Build it from scratch.
I have done it using the official Debian/Devuan tools debootstrap and chroot.
2) However, there's a ridiculously simple, "easier done, than said" method.
You can use any Debian Wheezy (or Jessie, but Wheezy would be better) and upgrade it
so the "2 options" are "build with debootstrap" and "upgrade from debian?"
well over a year ago, i downloaded devuan as an iso and installed it from cd. ive done that with pre-alpha, alpha2, alpha4, and beta.
each time, it has installed devuan.
also installing gnuinos or refracta will give you devuan (with the devuan repos.) and the unofficial-devuan-live iso from the refracta site will give you a devuan installation.
so there are actually 4 ways to get devuan on your computer:
1. deboostrap (this is the original way, and it still works)
2. upgrade from debian by changing debian to devuan repos
3. (since february of last year, or 19 months ago) its been possible to install devuan from an .iso
4. you can install one of the devuan-based isos. most of these will give you a different desktop than devuan (refracta and devuan come with xfce4) but unofficial-devuan-live is based on a snapshot of devuan.
given that theres been an installer iso for a year, im surprised anyone that knows how to debootstrap it thinks it is still necessary to do it that way.
anyway no-- you can install devuan the same way you install debian.
a glitch in the latest installer configuration requires you to have a network connection when you install (thats one of many reasons i use a live version) but other than that its exactly like the debian installer iso.
you can find the latest devuan isos here: https://files.devuan.org/devuan_jessie_beta/
since they have decided to remove older versions from their server, ally of the puppy linux forum is kind enough to mirror them here: https://archive.org/download/Devuan_Linux
