While installing Devuan from the new Jessie-beta .iso I noticed a couple of things wrong or missing:

1. The installer prompts for user creation (username and password) just after root password setup, but does not later install the sudo package, nor is the user put into the "sudoers" group.
2. The choice of "non-free" and "contrib" repositories is entirely removed from the installer, though such repositories exist and can be later enabled in /etc/apt/sources.list.
3. wpa_supplicant is installed by default, but the /etc/wpa_supplicant/wpa_supplicant.conf config is missing entirely.

There might've been more issues, but I probably ignored them as they were minor.
