I think none of our packages wants to write to /e/... No, but the packages you were installing *did* want to write to /etc, and we fail hard because we apparently prefix match and don't make sure it ends in a directory separator. Working on a fix, will submit a patch soon.
This is 100% reproducible: mkdir /e; mount something ro there, `pacman -S libao` or any other package that installs something in /etc. > I've tried > with both pacman 4.0.2-1 and pacman-git, the result is the same.
