RDCONFIG(8)             OpenBSD System Manager's Manual            RDCONFIG(8)

NAME
     rdconfig - configure RAM disks

SYNOPSIS
     rdconfig special_file 512-byte-blocks

DESCRIPTION
     The rdconfig command configures RAM disk devices.  It will associate the
     special file special_file with a range of user-virtual memory allocated
     by the rdconfig process itself.  The rdconfig command should be run in
     the background.  If successful, the command will not return.  Otherwise,
     an error message will be printed.

     To "unconfigure" the ramdisk, just kill the background rdconfig process
     started earlier.

FILES
     /dev/rrd??
     /dev/rd??

EXAMPLES
           rdconfig /dev/rd0a 2048 &

     Configures the RAM disk rd0a with one megabyte of user-space memory.

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