[RFC] Teaching mount(8) to use nmount()

[Craig Rodrigues]

Hi,

By the way, one side benefit of adding nmount() to mount(8)
is that we can eliminate unnecessary
mount_* binaries from /rescue and free up space.
For example, on my system:

-r-xr-xr-x  131 root  wheel  3256200 Oct  8 21:49 mount
-r-xr-xr-x  131 root  wheel  3256200 Oct  8 21:49 mount_cd9660
-r-xr-xr-x  131 root  wheel  3256200 Oct  8 21:49 mount_devfs
-r-xr-xr-x  131 root  wheel  3256200 Oct  8 21:49 mount_ext2fs
-r-xr-xr-x  131 root  wheel  3256200 Oct  8 21:49 mount_fdescfs
-r-xr-xr-x  131 root  wheel  3256200 Oct  8 21:49 mount_linprocfs
-r-xr-xr-x  131 root  wheel  3256200 Oct  8 21:49 mount_msdosfs
-r-xr-xr-x  131 root  wheel  3256200 Oct  8 21:49 mount_nfs
-r-xr-xr-x  131 root  wheel  3256200 Oct  8 21:49 mount_ntfs
-r-xr-xr-x  131 root  wheel  3256200 Oct  8 21:49 mount_nullfs
-r-xr-xr-x  131 root  wheel  3256200 Oct  8 21:49 mount_procfs
-r-xr-xr-x  131 root  wheel  3256200 Oct  8 21:49 mount_std
-r-xr-xr-x  131 root  wheel  3256200 Oct  8 21:49 mount_udf
-r-xr-xr-x  131 root  wheel  3256200 Oct  8 21:49 mount_umapfs
-r-xr-xr-x  131 root  wheel  3256200 Oct  8 21:49 mount_unionfs

I've found that mount_devfs, mount_std, mount_procfs, mount_fdescfs,
mount_nullfs, and mount_ext2fs are basically thin wrappers around nmount()
(i.e. no special arguments)  and can go right away.
