Author: asomers Date: Mon Jan 18 16:41:26 2016 New Revision: 294278 URL: https://svnweb.freebsd.org/changeset/base/294278 Log: MFC r292573 Fix "mount -a" for NFS and ZFS filesystems with shared mountpoints sbin/mount.c Check whether an fstab entry has the same fstype as a mounted filesystem before declaring it to be mounted. This will allow NFS filesystems that share a mountpoint with a local filesystem to be automatically mounted at boot. This is not such an unusual situation. For example, if somebody uses the standard installer with a ZFS root, he'll get a /usr/home filesystem, even though he may choose to mount /usr/home over NFS.
