                     13: .SH DESCRIPTION
                     14: .I Swapon
                     15: is used to specify additional devices on which paging and swapping
                     16: are to take place.
                     17: The system begins by swapping and paging on only a single device
                     18: so that only one disk is required at bootstrap time.
                     19: Calls to
                     20: .I swapon
                     21: normally occur in the system multi-user initialization file
                     22: .I /etc/rc
                     23: making all swap devices available, so that the paging and swapping
                     24: activity is interleaved across several devices.
                     25: .PP
                     26: Normally, the
                     27: .B \-a
                     28: argument is given, causing all devices marked as ``sw''
                     29: swap devices in
                     30: .B /etc/fstab
                     31: to be made available.
                     32: .PP
                     33: The second form gives individual block devices as given
                     34: in the system swap configuration table.  The call makes only this space
                     35: available to the system for swap allocation.

                     41: .SH BUGS
                     42: There is no way to stop paging and swapping on a device.
                     43: It is therefore not possible to make use of devices which may be
                     44: dismounted during system operation.
