From 7e3dd526c62b3a1bb59945efdfed2c2fbbcf9cf9 Mon Sep 17 00:00:00 2001 From: Niels de Vos Date: Mon, 23 Dec 2013 12:53:32 +0100 Subject: rpc/server: add anonuid and anongid options for root-squash Introduce new options to modify the behaviour of server.root-squash. With server.anonuid and server.anongid the uid/gid can be specified and the root user (uid=0 and gid=0) will be mapped to the given uid/gid instead of nfsnobody (uid=65534 and gid=65534). Many thanks to Vikhyat Umrao for writing the majority of the test-case!
