+.Sh NAME
+.Nm swapon
+.Nd "specify additional device for paging and swapping"
+.Sh SYNOPSIS
+.Nm swapon
+.Fl a
+.Nm swapon
+.Ar special_file ...
+.Sh DESCRIPTION
+.Nm Swapon
+is used to specify additional devices on which paging and swapping
+are to take place.
+The system begins by swapping and paging on only a single device
+so that only one disk is required at bootstrap time.
+Calls to
+.Nm swapon
+normally occur in the system multi-user initialization file
+.Pa /etc/rc
+making all swap devices available, so that the paging and swapping
+activity is interleaved across several devices.
+.Pp
+Normally, the first form is used:
+.Bl -tag -width Ds
+.It Fl a
+All devices marked as ``sw''
+swap devices in
+.Pa /etc/fstab
+are made available.
+.El
+.Pp
+The second form gives individual block devices as given
+in the system swap configuration table.  The call makes only this space
+available to the system for swap allocation.

+.Sh BUGS
+There is no way to stop paging and swapping on a device.
+It is therefore not possible to make use of devices which may be
+dismounted during system operation.
+.Sh HISTORY
+The
+.Nm
+command appeared in
+.Bx 4.0 .
