Target Hardware: i486DX CPUs (33MHz+) with 8MB RAM minimum
Latest Release: March 01, 2025
The philosophy is to create a completely hackable Linux system, controllable by makefiles.
SnackLinux features a minimalist kernel with downloadable kernel modules, optimized for systems with ISA expansion slots rather than PCI. Designed specifically for 486DX and higher processors (including Cyrix and AMD variants), it combines modern software capabilities with extreme optimization for size and low memory requirements. The distribution includes 40+ pre-built packages and a built-in package manager.
When building, the makefile process creates a fully customizable local rootfs directory; add any software, files, or modifications you want included in your final build for complete hackability. Think of it as Linux From Scratch with reduced complexity, perfect for minimal VMs or breathing new life into vintage hardware.
