It is a step in that direction, but by far not the final solution.  For your
case:  Yes, if your lab-config defines a

	class MyLab(lab.SSHLabHost):
	    def poweron(self, name: str) -> None:
	        ...

You could call it like that from your board config.

Both! If your machine is U-Boot

	with tbot.acquire_uboot(b) as ub:
	    ub.env("bootcmd", "bootm $loadaddr"

will set a U-Boot variable and if your machine is Linux

	with tbot.acquire_lab() as lh:
	    lh.env("ARCH", "arm")

will set an Environment Variable.

Personally I prefer no logfile by default, because you just end up with lots and
lots of logfiles in randon locations, that you probably won't ever take a look at ...
