ping 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

ization file /etc/rc making all swap devices available, so that the
paging and swapping activity is interleaved across several devices.
The second form gives individual block devices or files as given in the
system swap configuration table. The call makes only this space avail-
able to the system for swap allocation.
Note: "swap files" made with mkfile(8) can be used as swap areas over
