Introduction

The linux-tiny patchset is a series of patches against the 2.6 mainline Linux kernel to reduce its memory and disk footprint, as well as to add features to aid working on small systems. Target users are developers of embedded system and users of small or legacy machines such as 386s and handhelds.
