DESCRIPTION
The
md driver enables use of system or user memory as a disk. Memory for the disk must be allocated within the kernel or with
mdconfig(8) before the
md device may be used as a disk. Its behaviour is configured by the kernel options
MEMORY_DISK_HOOKS,
MEMORY_DISK_IS_ROOT,
MEMORY_DISK_ROOT_SIZE,
MEMORY_DISK_DYNAMIC, and
MEMORY_DISK_SERVER.
