# Hotplug physical memory. Instances of tmpfs are remounted so their
# size are recalculated. This might be needed if some sizes were
# specified relative to the total amount of memory (boo#869603). For
# now make it simple and remount all tmpfs regardless of how their
# size are specified. It should be handled by the kernel as it has a
# lot of shortcomings anyways (tmpfs mounted by other processes, mount
# namespaces, ...)
