Bug#742048: systemd-remount-fs.service fails for split-usr

[Victor Severtsev]

Having the same issue I've inspected systemd target dependency graph, it 
looks like this (in the start order omitting redundant 'hop' 
dependencies): systemd-remount-fs.service -> local-fs-pre.target -> 
usr.mount -> local-fs.target, therefore I consider this is a system 
configuration bug.

laptop-mode-tools is not installed, no manual configuration involved.
