MultiBoot USB
This is a project that contains a collection of GRUB files and scripts that will allow you to create a pendrive capable of booting different ISO files.
Void is an independently-developed, general-purpose operating system based on the monolithic Linux kernel. It features a hybrid binary/source package management system which allows users to quickly install, update and remove software, or to build software directly from sources with the help of the XBPS source packages collection. Other features of the distribution include support for Raspberry Pi single-board computers (both armv6 and armv7), rolling-release development model with daily updates, integration of OpenBSD’s LibreSSL software, and native init system called “runit”.
