-# desktops might have some/all 3 preinstalled, while servers tend not to have

 # 2022-03-15: This section is effectively now useless on RasPiOS (but apparently
 # serves a purpose on Ubuntu on RPi, where it installs dphys-swapfile and
 # fake-hwclock).  Still: @jvonau's above explanation of other OS's / other HW
 # suggest this code should possibly move in future, to helps others too?
