c783576970 Add a -o mountprog parameter to mount which explicitly allows
an alternative program to be used for mounting a file system.
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

3cbf527e8d Revert rev. 1.86 by jmallett@ as it breaks "ro" mounts specified
in /etc/fstab.

This has been happening due to the priority inversion; options
specified on the command line should take precedence over options
from fstab over default "noro" option, but since both the default
"noro" and options specified on the command line (-w, -r, -o ...)
were put into the same "options" variable, "noro" took precedence
over fstab "ro" (this is easily visible with "mount -d").

4b4f91707c Teach mount(8) about a 'late' keyword, which means the file system should
not be mounted unless the -l flag was specified.

Add an rc script, mountlate, which basically runs 'mount -a -l'.  It runs
after DAEMON but before LOGIN.

This is useful for things like loopback mounts, because mountcritremote
runs before mountd  / nfsd (since /usr might be a remote file system), so
an attempt to mount a loopback network file system in mountcritremote will
fail.

Also add a progress message to mountcritlocal, for the sake of symmetry
with similar messages in mountcritremote and mountlate.

88e2c33564 If we specify: mount -u (update), without specifying an
additional -r (read-only) flag or or -w (read-write) flag,
then assume we want, mount -u -w.

When doing a mount update, this will implicitly pass a "noro" mount
option down to the VFS layer.
vfs_mergeopts() in vfs_mount.c will then remove the "ro" mount option
if it exists in the mount options for a mounted file system.
This means that "mount -u" works the same as "mount -u -w"
and will convert a read-only mount to read-write.

7c5347ae86 Update text to reflect that:
- mount(8) now calls the nmount(2) system call directly, not mount(2)
- specifying a filesystem type with -t will not automatically
  invoke an external /sbin/mount_XXXX program....this only happens for
  certain file system types.  For all other file system types, nmount(2)
  is called directly.
