dd if=/dev/zero of=/tmp/swapfile bs=1024 count=5120000; mkswap /tmp/swapfile; swapon /tmp/swapfile

dd if=/dev/zero of=/tmp/swapfile bs=1024 count=5120000; mkswap /tmp/swapfile; mount /tmp/swapfile

dd if=/dev/zero of=/tmp/swapfile bs=1024 count=5120000; swapon /tmp/swapfile

dd if=/dev/zero of=/tmp/swapfile bs=1024 count=5120000; mkswap /tmp/swapfile; swapon /tmp/swapfile

touch -5G /tmp/swapfile; swapon /tmp/swapfile

mkswap /tmp/swapfile 512000; swapon /tmp/swapfile

It has configuration information, such as passwords and keys, for the remote file server.

It has configuration information on settings for the /home mount point.

It is the holds the SSL key to allow authentication to the remote file server.
