The file is installed to /usr/libexec/cvmfs/auto.cvmfs instead of /etc/auto.cvmfs (like rpm/deb installs) Arch links the file: https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=cvmfs I think we should either adjust the documentation on the client side https://wiki.gentoo.org/wiki/CVMFS or change the path for it to be consistent (or both).
