Coming four years after the Porteus 3.0 series, the Porteus 4.0 release ships with the latest Slackware Linux packages, it’s powered by the latest Linux 4.16 kernel branch (Linux 4.16.3 is included in the install images), and comes with no less than seven desktop flavors, including KDE, Xfce, LXDE, LXQt, Cinnamon, MATE, and Openbox. Porteus 4.0 features support for UEFI/EFI installations using the syslinux bootloader for both BIOS and UEFI/EFI machines with a single, universal configuration file that you can find in /mnt/sdXY/boot/syslinux/porteus.cfg. Also, a new porteus/porteus-v4.0-x86_64.cfg configuration file replaces the old .sgn file and adds support for cheatcodes.
