I don't recall for sure if that suffices to set the architecture for everything, or if there are other code adjustments that need to be made, however.

I have more of a hack and slash until something works approach to compiling than an actual programmer or software engineer does. but if it helps to know what I changed, I could probably learn with some pointers to the right set of docs.

Thanks for testing this. We're currently trying to push a major dpkg 
update out (one issue left AFAIK), and doing ARM will be the next thing 
to tackle afterwards.

A simple way to show changes is to make a copy of the original file your 
editing (Bootstrap.pm to Bootstrap.pm.orig, edit your changes, then run 
`diff -u Bootstrap.pm.orig Bootstrap.pm` to get the difference.

Out of curiousity, what's the output of this command on your M1 with 
your patched Fink?

fink --version
