I see.

Sounds good, but I haven't a clue how to do it.

Is this what you mean?

http://reboot.pro/topic/14547-linux-load-your-root-partition-to-ram-and-boot-it/

or how about this (this one is more opaque to me)?

https://www.kernel.org/doc/html/v4.17/admin-guide/initrd.html

after all the messing around I did to boot off a usb stick, it has just occurred 
to me that I could have done it by PXE boot, although I've never done it and 
haven't a clue how to do that either. I assume it's something like flashing a 
WAP, but I'd have to figure out how to make the image file.
