	Please consider the script (attached) for inclusion into Mtools.

	The script runs `dd', `mpartition' and `mformat' in sequence to
	construct a DOS hard disk image (i. e., with MBR) consisting of
	the specified number of DOS partitions of a given size.  E. g.:

$ grep -F x: -- ~/.mtoolsrc
drive x: file="/.../dos-exchange.image" partition=1
$ mkdosdisk /.../dos-exchange.image 640M
0+0 records in
0+0 records out
0 bytes (0 B) copied, 1.9639e-05 seconds, 0.0 kB/s
Warning: no active (bootable) partition present
$

	The above creates a DOS hard disk image consisting of a single
	640 MiB-long DOS partition with a filesystem, which is already
	configured as drive X: for Mtools.  Now, test it:

$ mcopy -s \
      ftp.glcf.umiacs.umd.edu/glcf/Landsat/WRS2/p148/r023/L71148023_02319990801.ETM-USGS \
      x:
$ mdir x:
 Volume in drive X has no label
 Volume Serial Number is 1959-D83D
Directory for X:/

$ mdir x:/L71148~1.ETM/

	And, once the image is no longer needed:

$ rm /.../dos-exchange.image
$

	I'm currently trying to use such a temporary partition to allow
	for large file sets to be transferred between a host GNU/Linux
	system and FreeDOS guests (running under, e. g., Qemu or KVM.)
