From 5ef28cccf92f5eada6d502fa4b0e16a13e94be5b Mon Sep 17 00:00:00 2001 From: William Wilgus Date: Fri, 3 Feb 2017 17:13:58 -0500 Subject: Allow mounting of any directory as the root directory. Provide definitions for the macros: * RB_ROOT_VOL_HIDDEN(v) to exclude certain items from the root. * RB_ROOT_CONTENTS to return a string with the name of the directory to mount in the root. Defaults are in export/rbpaths.h It's a bit much for those that don't need the full functionality. Some conditional define can cut it back a lot to cut out things only needed if alternate root mounts are required. I'm just not bothering yet. The basic concept would be applied to all targets to keep file code from forking too much.
