Arch: Move more of the things shipped by the distro to /usr/, too many things are still in /etc/, /var/ and /srv/. Generally this isn’t a problem, but when you want to make an A/B updated image where only /usr/ is shipped it is a bit annoying. Also, bash has no way to have a “distro” version of /etc/profile.

Another benefit is: no .pacnew files in /etc/ (or anywhere else) since those would all be managed by the system maintainer and aren’t touched by the package manager
