Comment # 1 on bug 866787 from Tom���� Chv��tal

Actually this is systemd feature.

Relevant commit upstream:

http://cgit.freedesktop.org/systemd/systemd/commit/?id=b3ac5f8cb98757416d8660023d6564a7c411f0a0

If you find this annoying feel free to file bug against systemd to change
default params for / to be different.
