aptitude why elogind should tell you why it's there. I don't know if there's an apt-get equivalent (in case you don't have aptitude.)

Maybe start with installing standard system utilities, and then add these. I'm not sure if you'll need the last two, and there are other parts of xfce4 that aren't necessary, but you might want them.

xfconf xfdesktop4 xfwm4 xfce4-panel xfce4-terminal xfce4-session xfce4-power-manager

I'm also not sure if it's still the case, but you might need to manually install dbus-x11 to avoid some conflicts.

Parallelized refers to services starting more or less all at the same time at boot. This was supposed to be a selling point for systemd when it was introduced, based on the belief that the system would boot faster. Sysvinit and openrc normally start services one after another. In practice, which method boots faster can vary.

The installer in the live isos copies the running live system to the hard drive. Since openrc is not installed in the current live isos, it won't be installed with the system. You can add it after you reboot into the new system. If openrc becomes the default init system in devuan at some time in the future, you will get it in the live isos, and in that case, if you want sysvinit, you'd have to add it after the initial installation.

If you want to install devuan with openrc on a lot of computers, you could make your own live iso with openrc. You would install the first system with sysvinit, change it to openrc, then run refractasnapshot to make a new iso. Then, any installs you did with the new iso would have openrc right from the start. I've already tried this, and it works.

Oops! I forgot that you asked about mate - there's no mate in the live isos. You would have to add that after you install the new system. The desktop-live only has xfce.

I just tried it. I started allowing javascript for several sites, went past my personal limit and then went totally crazy and turned off noscript (allowed all javascript). The noscript list of sites serving code on the page was so long, it went off-screen. That's reason enough to never go there again.

I was able to get audio, but no video. CPU temperature went up as if it had video.

I have browser-plugin-vlc and flashplugin-nonfree installed. I don't know if the flash plugin even works anymore. Last time I tried to install that for a friend, it was impossible. (It's no longer supported.)

Tested this on jessie.

The CD isos have fewer packages on them. You can install with just the first one for a small system, or you could use the additional ones for more packages. The DVD iso is a better choice.

If you select a mirror during the install, then you will essentially be doing a netinstall, and you'll get the full system. If you can do netinstall and you don't need to have the packages on a local optical disk, just get the netinstall iso.

You access the debian (devuan) installer by booting one of the installer isos. The live isos use refractainstaller, which won't do raid or lvm. You want one of these:

It's already in jessie. I see it in my i386 system and can download the package. In my amd64 system with multiarch, I can only download the amd64 version. Or maybe I don't know the right command to get it there.

If you're running ascii, you'd use libpng16-16.

The example script doesn't work because it does not get the mac address correctly. The output of ifconfig changed from jessie to stretch/ascii and no longer shows HWaddr.

Edit get-mac-address.sh and change

mac=$(/sbin/ifconfig "$iface" | sed -n -e '/^.*HWaddr \([:[:xdigit:]\-]*\).*/{s//\1/;y/ABCDEF/abcdef/;p;q;}')

to

mac=$(/bin/ip link | grep -A1 "$iface" | awk '/link/ { print $2 }')

Note: If your mac addresses have any upper case letters, the above line will need more than I can give you right now.

I think this is right, but I haven't tested it. See 'man interfaces' and also look at the files in /usr/share/doc/ifupdown/examples.

Copy the get-mac-address.sh script from the examples directory into /etc/network/interfaces.d/ and make it executable. Then edit the interfaces file like this:

auto enp3s0 enp2s0
mapping enp3s0 enp2s0
  script /etc/network/interfaces.d/get-mac-address.sh
  map 00:55:44:33:22:11 eth0
  map 00:11:22:33:44:55 eth1
iface eth0 inet dhcp
iface eth1 inet static
	address 192.168.1.17
	netmask 255.255.255.0
	network 192.168.1.0
	broadcast 192.168.1.255

I think that's still the right place to put your own rules, but I don't really know much about udev rules or what goes into them. Did you try using KERNEL=="enp*" instead of KERNEL=="eth*"? (just a guess)

Another possibility is to rename the interfaces in /etc/network/interfaces. See the section on MAPPING in man interfaces. You should be able to give them any names you want.

Install xinit. You might need to do this even if you install xorg, which is a metapackage that gives you all the drivers. Without that metapackage, make sure you have xserver-xorg-video-whatever, where whatever is the right one for the Pi3.

Here's some relevant infomation from the release notes:

All the live isos have non-free wireless firmware already installed (except for a few broadcom packages) and all the installer isos have non-free wireless and other firmware packages in /firmware in the iso.

For the icon sets that aren't working, check their Recommends, which are excluded by default. Something is probably missing.

If you want icons on the desktop and a background image, the easiest way to do it is to set spacefm to control the desktop.
