Squashfs is a highly compressed read-only filesystem for Linux 2.4. It uses zlib to compress files, inodes, and directories. All blocks are packed to minimise the data overhead, and block sizes of between 4K and 32K are supported. It is intended to be used as a filesystem for archival use and in embedded systems where low overhead is needed. 1.2 has added append capability to Mksquashfs. This means that new files and directories can be added to pre-existing filesystems without needing to rewrite the original data. For large filesystems this can be of major benefit. Because mksquashfs peforms duplicate checking against the original filesystem, it means that updated directories can be appended over time, and only the changed files will take extra space. The unchanged files will be detected as duplicates, and will share data. This exhibits a basic versioning capability. Squashfs1.2 is available from http://squashfs.sourceforge.net.
