Make it work. Basic BSD shell doesn't seem to have array support (read
failed and ${!VAR[@]} as well). Also I don't know integer arithmetic so
I do a runtime length for the loop.
As we don't put $MACHINE/$RELASE into an `` block we should be okay
and not run into remote execution.
This is not tested and will be debugged on the server. Begin to
automate the on-server setup so we can make this a self-service
without much user interaction.
