FS_MAPPER

The FS_MAPPER feature provides support for swap in the system. It requires either the SCSI_DISK to be configured, as well as VIRTUAL_ADDRESS_SPACE. Swap is only supported on local disks. Swapping to a remote device or file over NFS is not supported. This feature uses a dedicated file system layout on disks.

The FS_MAPPER feature exports the swapon() system call.

For details, see the FS_MAPPER(5FEA) man page.
