Install the package as follows: `pacman -S filesystem --force` It is strongly advised to avoid the `--force` or `-f` switch as it is not safe. However, in this particular case it is needed as deleting `/etc/mtab` manually would break pacman. The reason for the conflict is that the file used to be generated at boot and hence not owned by any package. Now it is a symlink to `/proc/self/mounts` owned by `filesystem`. This change means that `initscripts` no longer requires write access to the rootfs (though other packages might). URL: http://www.archlinux.org/news/filesystem-upgrade-manual-intervention-require...
