I just watched the excellent 10 Years of Guix talk "Guix REPL—to 
infinity and beyond".

I am not sure if you are the same Simon, but it made me wonder if 
using guix extension could a nice way to solve these sorts of 
problems.

Could I have a set of guix extensions local to each project so 
that I can run commands like:

guix serial-shell PORT=/dev/ttyUSB0

Which would really run something like:

guix time-machine -C .channels.scm -- shell --container 
--expose=$(PORT) -- make PORT=$(PORT) serial-shell

Where some Makefile defines serial-shell:

serial-shell
  picocom -b 9600 -f n -y n -d 8 -p 1 -c $(PORT)

Maybe the path of the Makefile would need to be specified in the 
extension somewhere.

That way non-guix users can just run the Makefile and guix users 
only need to use the guix command. Or maybe the extension could 
call a shell script if that is better for non-guix users than 
running a Makefile.
