It's what our default loader/entries/arch.conf uses. Of course, it's
suboptimal when booting multiple installs.

When booting with at least systemd 198, kernel 3.8, and gummiboot 11,
the ESP will be mounted at /boot by default. No fstab configuration
necessary. Having a non-empty /boot or a configured mount disables
this feature.

The systemd guys are cooking up a kernel-install tool which installs
the kernels into an installation-specific subdirectory in /boot (based
on machine-id) and automatically writes loader entries for them. I
hope we can make use of this in the future.
