FUSE filesystem to mount squashfs archives

squashfuse - Mount SquashFS archives using FUSE https://github.com/vasi/squashfuse Squashfuse lets you mount SquashFS archives in user-space. It supports almost all features of the SquashFS format, yet is still fast and memory-efficient. So that everyone can use it, squashfuse supports many different operating systems and is available under a permissing license. SquashFS is an efficiently compressed, read-only storage format. Support for it has been built into the Linux kernel since 2009. It is very common on Live CDs and embedded Linux distributions. Quick start: $ ./configure && make $ ./squashfuse foo.squashfs mountpoint 1. Table of contents ==================== 0. Introduction 1. Table of contents 2.

References - Licensing - Acknowledgements - Links 2. Getting started ================== 2a. System requirements ----------------------- To build and use squashfuse, you must be able to use the terminal of your operating system. Runtime requirements: - FUSE 2.5 or later - At least one of the following compression libraries - zlib - lzo2 - xz (aka. liblzma) - lz4 - zstd - (optional) libattr, for better extended attribute support on Linux Build requirements: - A C compiler - make (any variant) - sed - (optional) pkg-config, for detection of dependencies To build from the development repository, rather than a tarball, you'll need: - autoconf 2.60 or later - automake 1.11 or later - libtool 2 Known fully-supported platforms: - Linux - Mac OS X - FreeBSD - NetBSD - OpenIndiana - Android - other platforms may work too! For a precise list of packages you will need on your OS, and other platform notes, please see the file `PLATFORMS'. 2b. Getting the source ---------------------- The squashfuse distribution can be downloaded from SourceForge: https://sourceforge.net/projects/squashfuse/files/ The development repository uses git, at GitHub: http://github.com/vasi/squashfuse 2c. Installation ---------------- Squashfuse is built with the usual `configure && make'. If you need more detailed instructions: 0. Ensure you're at your terminal, in the directory containing this README. 1. (if needed) If the file `configure' is already present, skip this step. Otherwise, run `./autogen.sh' to generate one. 2. Run `./configure' to set up the build. You can find useful configuration options in the file `CONFIGURATION', or by running `./configure --help'. If configure fails, check that you really have all the requirements installed. You may also want to check the `PLATFORMS' file to see if there are any special notes for your operating system. 3. Run `make' to build `squashfuse'. 4. (optional) If you want to use squashfuse in this directory, that's ok. But if you'd rather install it, run `make install'. If you need root privileges, `sudo make install' may work. 2d. Example: Ubuntu ------------------- For example on Ubuntu 16.04: sudo apt-get -y install git autoconf libtool make gcc libtool libfuse-dev liblzma-dev libtoolize --force aclocal autoheader automake --force-missing --add-missing autoconf ./configure --with-xz=/usr/lib/ make 2e. Usage --------- You'll need a SquashFS archive to use squashfuse. If you don't already have one, you can create one using the `mksquashfs' utility from the squashfs-tools project. To create a SquashFS archive: $ mksquashfs DIRECTORY ARCHIVE To mount a SquashFS archive with squashfuse: $ squashfuse ARCHIVE MOUNTPOINT To unmount when you're done: $ umount MOUNTPOINT # On Mac/BSD $ fusermount -u MOUNTPOINT # On Linux For more options, see the man page squashfuse(1). 3. About squashfuse =================== 3a. Is squashfuse for you? -------------------------- Squashfuse is a great option if you have a SquashFS archive, and: - You're not running Linux, or - You don't have root access, or - You're too concerned about security to use root, or - You find it inconvenient to elevate privileges, or - SquashFS is not built into your kernel, but FUSE is, or - You want to hack on the SquashFS format without risking kernel panics. Squashfuse is probably not the right tool for the job, if: - You don't have FUSE. More and more systems have FUSE, but some don't. Squashfuse requires it. - You have a very old SquashFS archive. Neither squashfuse nor the Linux kernel support SquashFS versions less than 4.0. Use `unsquashfs' from the squashfs-tools project. - You want to create or modify a SquashFS archive. Neither squashfuse nor the Linux kernel support write access, use `mksquashfs' from squashfs-tools. - You want to extract an entire SquashFS archive. If you don't want to mount anything, it's more efficient and convenient to just use unsquashfs. - You want your root filesystem `/' to be SquashFS. This isn't well-tested, though it may be possible. - You're highly concerned about bugs. The SquashFS kernel module has seen much more testing than squashfuse. If you don't yet use SquashFS, consider starting, now that squashfuse exists. For many uses, the chief drawbacks of SquashFS were requiring Linux and root access, but squashfuse has that covered. - Use SquashFS for archival and backup, instead of tar. It offers faster creation (multi-core), and browsing without unpacking. - Use SquashFS instead of zip. It has better compression, and faster directory lookup. - Use SquashFS instead of compressed disk images like DMG, uzip or Partimage. It has better compression and portability. 3b. What's included? -------------------- Squashfuse currently comprises three programs: * squashfuse Allows you to mount a squashfs filesystem. * squashfuse_ll Like `squashfuse', but implemented using the low-level FUSE API. It's a tiny bit faster, but less portable. * squashfuse_ls Lists all the files in a squashfs archive. A demonstration of using the squashfuse core in the absence of FUSE. 3c. Features ------------ Squashfuse supports the following SquashFS features: - zlib, LZO, LZMA2, LZ4 and zstd decompression - Fast, indexed directory lookup - Fast, indexed seeking within files - Caching of decompressed blocks - De-duplicated files - Sparse files - Extended attributes - Files larger than 4GB Squashfuse is missing the following features: - LZMA1 compression (deprecated) - Support for SquashFS versions less than 4.0 - Multi-core decompression 3c. Known bugs -------------- - On 32-bit systems with a large inode cache, when mounting a large SquashFS archive created with the "-no-exports" option, squashfuse_ll may use a large amount of memory. This is due to a bug in the FUSE API, where ino_t is shrunk to 32-bits. 4. References ============= 4a.
