Source: debian-policy Version: 4.3.0.1 At the end of https://www.debian.org/doc/debian-policy/ch-opersys.html#file-system-hierarchy there is a link named FHS (Debian copy) pointing to https://www.debian.org/doc/packaging-manuals/fhs/
but that is the FHS 2.3 version and Debian Policy in that same section (ยง9.1.1) says that Debian follows FHS 3.0. I see that the Debian package for debian-policy does install the 3.0 version, so it's just the website that needs to be updated. Thanks, Jeremy Bicha
