rev. 1.52-1.54 mdconfig.c

Make attach the default for -f and assume '-a' and '-t malloc' flags for '-s
<size>' (malloc ramdisk) if not specified.

To mount an image:

MD=mdconfig -f image
mount $MD /mnt

To create and mount a RAM disk (gosh, last I used those was on an Atari 1040ST:
256kb just to piss off the 640kb PC loosers)

MD=mdconfig -s 5mb
newfs /dev/$MD
mount /dev/$MD /mnt

Et voila! Much easier to remember.
