to specify devices for swapping
The device or file used is given by specialfile . May be of the form
-L label or
Calls to swapon normally occur in the system multi-user initialization file
/etc/rc making all swap devices
available, so that the paging and swapping activity is interleaved across several devices and files.
Normally, the first form is used:
swapoff disables swapping on the specified devices and files. When the -a flag is given, swapping is disabled
on all known swap devices and files (as found in /proc/swaps or /etc/fstab).
Do not use swapon on a file with holes.
Swap over NFS may not work.
