Occasionally I need to run two node servers on two different Amber Smalltalk checkouts and it would be real convenient to be able to control this via the startup script, but my read of the startup script tells me that I'll have to edit some code, which is not ideal.
in server/FileServer.st - after you have updated it there - I think there is a Makefile in that same dir to help you recompile
So there's no way to do it (currently ~ Amber 0.9.3) without editing a file directlty.
