history

Project history and usage

acl is the Linux access control list package, providing commands and library support for POSIX-style filesystem ACLs.

Project history

The Savannah README identifies acl as the access control list package and points to acl(5) for general ACL information. The man pages document getfacl, setfacl, chacl, and the ACL library interfaces.

The setfacl manual carries 2000 documentation copyright, while the acl(5) manual describes POSIX Access Control Lists as finer-grained discretionary access rights for files and directories. The official changelog tracks the modern package line from early 2.2 releases through later security, portability, and build-system work.

Adoption history

acl is widely packaged because it exposes common filesystem administration tools rather than an application-specific workflow. The input facts list it in Homebrew, Debian, Ubuntu, Fedora/dnf, Alpine, Arch/pacman, Nix, and openSUSE/zypper.

Its package history follows the Unix pattern of small core utilities with man pages, C library APIs, and distribution integration, especially around getfacl/setfacl behavior, symlink handling, restore mode, translations, and filesystem semantics.

How it is used

Typical use is administrative: getfacl prints ACLs, setfacl sets or restores ACLs, and chacl changes ACLs on files and directories.

Because ACL behavior is tied to filesystem support and Unix permissions, the package is usually used by scripts, sysadmins, packaging tests, and tools that need reproducible permission metadata.

Why package nerds care

acl is package-nerd significant because it is small, old, security-sensitive system plumbing. A packaging error can affect backups, restores, permissions, and recursive filesystem operations.

It is also a classic example of Linux userland split into a library plus command-line tools, with man pages carrying much of the public interface contract.

Timeline

  • 2000: setfacl manual documentation copyright begins.
  • 2002: acl(5) manual documentation copyright begins.
  • 2003: Official changelog records acl 2.2.5 and related libacl changes.
  • 2009: acl 2.2.48 fixes recursive symlink and restore behavior.
  • 2021: acl 2.3.0 modernizes build infrastructure and hardens recursive operations.
  • 2026: acl 2.4.0 changelog records security and robustness improvements.

Related projects

  • Related system components include Linux filesystems, POSIX permission bits, extended attributes, libacl, getfacl, setfacl, and chmod.
