Not all kernels have (working) getrandom support

Browse Source 
hammerhead 16.0 was reported not booting
and shamu 18.1 was reported to take ~15+ minutes to boot

hammerhead does not have getrandom so it failed immediately

shamu does have getrandom BUT it blocks during init
meaning it'll wait until the entropy pool slowly fills

In tested I did not discovery this
I tested on flox/mako/d852/klte/clark/sailfish/mata/cheeseburger/fajita
All the newer ones have working getrandom
All the older ones included a patch to make getrandom non blocking on init
