| 17 | .SH DESCRIPTION | |
| 18 | .I Swapon | |
| 19 | is used to specify additional devices on which paging and swapping | |
| 20 | are to take place. | |
| 21 | The system begins by swapping and paging on only a single device | |
| 22 | so that only one disk is required at bootstrap time. | |
| 23 | Calls to | |
| 24 | .I swapon | |
| 25 | normally occur in the system multi-user initialization file | |
| 26 | .I /etc/rc | |
| 27 | making all swap devices available, so that the paging and swapping | |
| 28 | activity is interleaved across several devices. | |
| 29 | .PP | |
| 30 | Normally, the | |
| 31 | .B \-a | |
| 32 | argument is given, causing all devices marked as ``sw'' | |
| 33 | swap devices in | |
| 34 | .B /etc/fstab | |
| 35 | to be made available. | |
| 36 | .PP | |
| 37 | The second form gives individual block devices as given | |
| 38 | in the system swap configuration table. The call makes only this space | |
| 39 | available to the system for swap allocation. | |

| 45 | .SH BUGS | |
| 46 | There is no way to stop paging and swapping on a device. | |
| 47 | It is therefore not possible to make use of devices which may be | |
| 48 | dismounted during system operation. |
