I am wondering about this same concept.
I am working on final tweaking tuning of an application running on a RUT 955
there are a number of shell scripts, config files, modbus data requestors, etc.
is there a simple systematic way to capture all of the stuff which has been changed/tweaked
into a file or a few files and then expand/extract all those bits and pieces basically making a clone of the new modified system config
on a brand new stock RUT955? I'm thinking particularly of all the modbus requestors which would have to be hand-built.
