Binary package “dphys-swapfile” in ubuntu xenial

Autogenerate and use a swap file

 This init.d script exists so one does not need to have a fixed size
 swap partition. Instead install without swap partition and then run this,
 with file size (re-)computed automatically to fit the current RAM size.
 By default (and hence on installation) it creates swapfile twice as
 big as the present RAM amount with an upper limit of 2 GB.
