Thanks for walking me through that.  I've made the changes to
50-local.conf and initramfs.conf and rebooted.  sysctl is now reporting
this:

	vm.swappiness = 0
	vm.vfs_cache_pressure = 50

We'll see how that goes for this kernel:

	Linux lubuntu 3.11.0-8-generic #15-Ubuntu SMP Fri
	Sep 20 04:11:26 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
