append the setdir ("5.7/amd64", "snapshots/vax") as get-parameter "path"

append the setdir ("5.7/amd64", "snapshots/vax") as get-parameter "path"
when fetching the autoinstall response file.
a webserver that serves static files doesn't give a damn. if I map that
to something that dynamically creates the response file, i can use that to
construct the sets path, or play other arch and/or version dependent
games.
