MDCONFIG(8)		  BSD System Manager's Manual		   MDCONFIG(8)

NAME
     mdconfig — configure MEMORY disks

SYNOPSIS
     mdconfig special_file 512-byte-blocks

DESCRIPTION
     The mdconfig command configures memory disk devices.  It will associate
     the special file special_file with a range of user-virtual memory allo‐
     cated by the mdconfig process itself.  The mdconfig command should be run
     in the background.	 If successful, the command will not return.  Other‐
     wise, an error message will be printed.

     To "unconfigure" the memory disk, just kill the background mdconfig
     process started earlier.

FILES
     /dev/rmd??
     /dev/md??

EXAMPLES
	   mdconfig /dev/md0c 2048 &

     Configures the memory disk md0c with one megabyte of user-space memory.

SEE ALSO
     mount(8), swapon(8), umount(8)

BUGS
     The special device will become inoperative if the mdconfig process is
     killed while the special device is open.
