Ben Gras 647e179038 . release fixes
. added OPENCT ioctl to at driver, which returns the number of times
  a device is opened. if it's not opened exactly once, new partition info
  will not be read in (at the next open after this close). included
  this check in autopart.

MINIX needs one primary partition of about 250 MB for a full install.
The maximum fill system currently supported is 4 GB.
If there is no free space on your disk then you have to choose an option:
(1) Delete one or more partitions
(2) Allocate an existing partition to MINIX 3
(3) Exit setup and shrink a partition using a different OS
To make this partition you will be put in the editor \"part\". Follow the
advice under the '!' key to make a new partition of type MINIX. Do not
touch an existing partition unless you know precisely what you are doing!
Please note the name of the partition (e.g. c0d0p1, c0d1p3, c1d1p0) you
make. (See the devices section in usage(8) on MINIX device names.)
