[Nix-dev] X11 rtkit.service and failing nixos-rebuild

[Ruben Astudillo]

Hi all

On nixos-16.09, in two different machines, the nixos-rebuild test
command fails with the following error

cannot open
`/nix/store/cjj8nc08bc799w4c6a4lw7r2z25q2jya-xorg-server-1.18.3/share/X11/xkb/compiled/systemd-private-0bc0e7c988b74d5ba0c9927a95747999-rtkit-daemon.service-iJMQaO':
Permission denied at
/nix/store/9g4wc31j7a2xp22xpgwr0qssfxahxdzl-builder.pl line 58.

checking such file, it doesn't seem different in permissions than the
rest of them. Anybody with a similar experience on recent builds?
