The command set is commonly used by administrators, packaging scripts, and filesystem tests that need explicit xattr operations. ### Why package nerds care attr matters to package nerds because it is the user-visible companion to filesystem metadata features that otherwise hide behind kernel and libc interfaces. Its tiny CLI surface makes it a common dependency in system images and test environments. ### Timeline - 2.4.x: Official git refs include late 2.4 series release tags. - 2.5.x: Official git refs include 2.5 series release tags. - 2.6.0: Official git refs include a v2.6.0 release tag. ### Related projects - Filesystem extended attributes are exposed by Linux filesystems and consumed by tools such as backup, security-labeling, and packaging utilities. - The Linux ACL tooling is a nearby low-level filesystem metadata package family. ### Sources - - - official git tags from https://git.savannah.nongnu.org/git/attr.git - source_facts.package-manager ## Security Notes narrow executable package without higher-risk signals. -
