MDCONFIG(8)             NetBSD 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.
