It +compresses files, inodes, and directories with one of several compressors. +All blocks are packed to minimize the data overhead, and block sizes of +between 4K and 1M are supported. It is intended to be used for archival use, +for live media, and for embedded systems where low overhead is needed. + +The squashfs-tools-ng package offers alternative tooling to create and extract +such file systems. It is not based on the older squashfs-tools package and +its tools have different names: + +@enumerate +@item @command{gensquashfs} produces SquashFS images from a directory or +@command{gen_init_cpio}-like file listings and can generate SELinux labels. +@item @command{rdsquashfs} inspects and unpacks SquashFS images. +@item @command{sqfs2tar} and @command{tar2sqfs} convert between SquashFS and +tarballs. +@item @command{sqfsdiff} compares the contents of two SquashFS images. +@end enumerate + +These commands are largely command-line wrappers around the included +@code{libsquashfs} library that intends to make SquashFS available to other +applications as an embeddable, extensible archive format. + +Both the library and tools operate deterministically: same input will produce +byte-for-byte identical output.") + ;; Upstream goes to some lengths to ensure that libsquashfs is LGPL3+. + (license license:gpl3+))) + (define-public pigz (package (name "pigz") |
