if you want to fallback to default pacman.config, then all you need is this
(match pacman_config with
| None -> ""
| Some filename when Sys.file_exists filename -> " --config " ^ filename
| _ -> ""
)
if you believe that febootstrap should exit, then i dont mind to
(learn more ocaml) provide a patch in the next few days.
Thats why i asked about the yum plugin approach on yum config file.
