Under Debian you can run GNOME under other init systems thanks to Debian+Canonical creating systemd-shim (alternative to logind). Under Devuan you cannot use GNOME (they don't offer it). This as Devuan claims that it is impossible (despite being possible within Debian) (!)
This task package is used to install the Devuan desktop,
featuring the GNOME desktop environment, and with other
packages that Devuan users expect to have available on the
desktop.
