From 2d77e3a27b7b211f303fcc3a813a044838dad970 Mon Sep 17 00:00:00 2001 From: Steve Dickson Date: Sat, 19 Jan 2008 07:59:26 -0500 Subject: [PATCH] Fix bug when both crossmnt and fsid are set. When exported a filesystems with option inherited (by the crossmnt option) from a higherlevel filesystem, ignore filesystem specific options like FSID and explicit UUID.
