Reservations
From Indian Libertarians Wiki
The libertarian position on reservations is pretty clear. Libertarians are opposed to government interference in private business. Therefore are opposed to mandating reservations in private jobs.
In education, libertarians are opposed against government in education especially running colleges/universities. So the issue of reservations becomes a moot point In private colleges, libertarians strongly oppose forcing reservations on private colleges as that is a violation of their private property rights.
