archive2sqfs is a tool to convert an archive to a SquashFS image. archive2sqfs is currently usable, but not yet feature-complete.

What works?

• directories, regular files, symlinks, sockets, pipes, device files
• fragments
• deduplication
• gzip compression
• zstd compression

What doesn't work?

• extended attributes
• sparseness
• directory indexes
• lzma, lzo, lz4, and xz compression

Why couldn't I just use mksquashfs?

• Maybe you don't have the space to unpack the archive.
• Maybe you want the output to be reproducible.

How do I build it?

cmake .
make

There are optional dependencies, enabled via CMake variables:

• USE_ZSTD=1 enables zstd compression via libzstd.

How do I use it?

archive2sqfs [--strip=N] [--compressor=<type>] [--enable-dedup] [--single-thread] outfile [infile]

• The --strip option removes leading directories from archive entries.
• If the infile parameter is omitted, the input archive will be read from stdin.
