ANNOUNCEMENT: Squashfs released (a highly compressed filesystem)

From: Phillip Lougher (
Date: Tue Oct 29 2002 - 21:29:01 EST


First release of squashfs. Squashfs is a highly compressed read-only
filesystem for Linux (kernel 2.4.x). It uses zlib compression to
compress both files, inodes and directories. Inodes in the system are
very small and all blocks are packed to minimise data overhead. Block
sizes greater than 4K are supported up to a maximum of 32K.

Squashfs is intended for general read-only filesystem use, for archival
use, and in embedded systems where low overhead is needed.

Squashfs is available from

The patch file is currently against 2.4.19. There is further info on
the filesystem design etc. in the README.

I'l be interested in getting any feedback, advice etc. on it.
