MultipleKlipperInstancesInOneRepository

update:

sigh, can't really do this. was a good (or bad?) idea.

The basic concept here is: set the startup in

 /etc/systemd/system/klipper.service

to point to a system-uniquely named printer.cfg file instead of the generic printer.cfg file. Thus, instead of

 Environment=KLIPPER_CONFIG=/home/pi/klipper_config/printer.cfg

you would, for example, use

 Environment=KLIPPER_CONFIG=/home/pi/klipper_config/printer-elf.cfg

This single-line change will allow for a unified repository, with unified macros and anything else that you want to have common.

the newest version of the kliper install changes this; the environment line in the klipper.service file

 EnvironmentFile=/home/pi/printer_data/systemd/klipper.env

so the strategy changes. for example:

normal install of mainsail via raspberry pi installer
in printer-data/systemd/klipper.env replace printer.cfg with stumpy/printer.cfg
move printer-data/config out of the way, rename to config.orig perhaps
check out the klipper-farm repo, which needs to contain a subdir called stumpy
reboot, and pray!
