While accessing this
will be slightly slower than dedicated swap partitions (due to
fragmentation and filesystem overhead), it is ideal for solving a
temporary swap shortage. To add 10 MBytes of swap space is as easy as selecting a filesystem
with sufficient free space and: # dd if=/dev/zero bs=1m count=10 of=/somefilesystem/swap # chmod 600 /somefilesystem/swap # swapctl -a -p 1 /somefilesystem/swap The dd(1) command creates a 10 MByte file
` /somefilesystem/swap '.
