Arch Linux Filesystem
The Arch Linux operating system sets out a filesystem standard that it maintained by the pacman(8) package manager the filesystem package. Breaking changes will be caught during upgrades and may trigger a failure.

All system-level binary directories (including /sbin) are links to /usr/bin, and all system-level library directories are links to /usr/lib.
The local directory mirrors the usr directory, except that manual pages are pulled to the top-level instead of being nested under share.
The true runtime directory is /run, though legacy links are also created.
Files
The filesystem package also installs a number of default configurations. These will commonly be edited and overwritten by users without leading to any breakage in the Arch Linux environment, so there's little purpose to documenting them.
