It's not really my use case, I'm just forwarding a question i got, so
I might not get all details right.
I can load and run code on a remote node and it executes just fine.
The problem is that if I start the debugger and set a breakpoint, it's
getting activated only if the remote node shares filesystem with the
local machine. Looking at the debugger code, I see that the
interpreter uses read_file to load the code to interpret, which would
explain the behaviour.
What I'd like to know is if there is something I missed or do wrong
and this can be made to work in all cases, or if there's a built-in
limitation of the debugger (which would be useful to document).

Thanks, I know, I use it too sometimes.
