addition to the plain command line image, there is a graphical flavor with the XFCE desktop environment. Other graphical environments are fully supported by Void Linux, but are not offered as demonstration/installation images, in order to decrease the overhead involved with testing.
Installable live images support a local installation (with the included packages) or a network installation (packages are downloaded from official repository).
You can log into these images as anon or root, and the password is voidlinux.
To start the installer, execute the void-installer utility with appropriate permissions (i.e., sudo void-installer).
