.Sh NAME
.Nm rdconfig
.Nd configure RAM disks
.Nm mdconfig
.Nd configure MEMORY disks
.Sh SYNOPSIS
.Nm rdconfig Fl c
.Nm mdconfig Fl c
.Op Fl v
.Ar special_file
.Ar 512-byte-blocks
.Sh DESCRIPTION
The
.Nm rdconfig
command configures RAM disk devices.
.Nm mdconfig
command configures memory disk devices.
It will associate the special file
.Ar special_file
with a range of user-virtual memory allocated by the
.Nm rdconfig
.Nm mdconfig
process itself. The
.Nm rdconfig
.Nm mdconfig
command should be run in the background.
If successful, the command will not return.
Otherwise, an error message will be printed.
.Pp
To "unconfigure" the ramdisk, just kill the background
.Nm rdconfig
To "unconfigure" the memory disk, just kill the background
.Nm mdconfig
process started earlier.

.Pp
Configures the RAM disk
.Pa rd0a
Configures the memory disk
.Pa md0a
with one megabyte of user-space memory.
.Sh BUGS
The special device will become inoperative if the
.Nm rdconfig
.Nm mdconfig
process is killed while the special device is open.
