OK, I get it, you mean that the later code falls back to AUR.
That could happen. I think what is needed is an explicit
check earlier on, ie:
fun pkg ->
if not (Sys.file_exists filename) then
failwith (sprintf "%s: pacman-config file does not exist" filename)
else (
... all the rest of the code ...
)
