8 is max, depending on the mood its in it might show 0% for hours at a 
time, that particular outlet, checked with a kil-a-watt is below what 
the kil-a-watt can read. Does not include an 11 watt monitor but does 
include everything else powered by a 5 volt, 5 amp supply, which is a 
7i90FD interface card and the three 7i40TA cards that buffer the fpga's 
puny outputs in addition to the rpi4b. That power level doesn't bither 
me a bot. All machine power is controlled by the rpi4b, it controls 2, 
60 amp SSR's that switch off the 240 to the machine if linuxcnc is not 
running, and it wasn't when the shell freeze occurred.

journald can't be found, by me or root.
