mount -o remount,rw /usr

Also, while this isn't yet in a stable release, see:
https://github.com/GNOME/ostree/pull/182
which makes live-editing the fs safe.

In the meantime, be careful to e.g. use `install` over `cp` to replace
files.  The latter will truncate-in-place (open(..., O_TRUNC)) and corrupt hardlinks.

I'll try at some point to put together some "hacking atomic host"
docs.
