SYNOPSISmdconfig 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.
