The two options are
* nocover/cover: Prevent/allow mounting over an existing root mountpoint.
E.g., "mount -t ufs -o nocover /dev/sd1a /usr/local" will fail if /usr/local
is already a mountpoint.
* emptydir/noemptydir: Prevent/allow mounting on a non-empty directory.
E.g., "mount -t ufs -o emptydir /dev/sd1a /usr" will fail.
Neither of these options is intended to be a default, for historical and
compatibility reasons.

should use more extensive checks on the file-system's metadata
before using it. This option is intended to be used when mounting
file systems from untrusted media such as USB memory sticks or other
externally-provided media.
It will initially be used by the UFS/FFS file system, but should
likely be expanded to be used by other file systems that may appear
on external media like msdosfs, exfat, and ext2fs.

it wants to use the statfs information cached in the mount structure.
When the -v (verbose) flag is specified, we need to use the MNT_WAIT

current statfs statistics from each filesystem.

Mainly focus on files that use BSD 3-Clause license.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.
This basically makes "mount -uw /" work when the filesystem
mounted on / is NFS, but the one configured in fstab(5) is UFS,
which can happen when you forget to modify fstab.
Note that the whole special case ("else if (argv[0][0] == '/'")
is probably not needed anyway. I'll take a look at removing it
altogether; for now this is a minimally intrusive fix.

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.

NFS client (which I guess is no longer experimental). The fstype "newnfs"
is now "nfs" and the regular/old NFS client is now fstype "oldnfs".
Although mounts via fstype "nfs" will usually work without userland
changes, an updated mount_nfs(8) binary is needed for kernels built with
"options NFSCL" but not "options NFSCLIENT". Updated mount_nfs(8) and
mount(8) binaries are needed to do mounts for fstype "oldnfs".
The GENERIC kernel configs have been changed to use options
NFSCL and NFSD (the new client and server) instead of NFSCLIENT and NFSSERVER.
For kernels being used on diskless NFS root systems, "options NFSCL"
must be in the kernel config.
Discussed on freebsd-fs@.
We'll start noticing this with the next flag introduced as the lower
32bit are all used.
As this is old code we might need to do a full tree sweep one day, unless
changing our strategy to use a different `API' for getting/setting flags
along with the rest of the statfs data.
While here compare to 0 explicitly [1].

Ideally, all file systems
should be converted to pass string arguments to nmount(), so that
/sbin/mount can handle them. However, certain file systems such as FUSE have
not done this, and want to have their own userland mount programs.
For example, to mount an NTFS file system with the FUSE NTFS driver:
mount -t ntfs -o mountprog=/usr/local/bin/ntfs-3g /dev/acd0 /mnt
or via an fstab entry:
/dev/acd0 /mnt ntfs ro,noauto,mountprog=/usr/local/bin/ntfs-3g 0 0
