Ensures a swapfile exists or is created on the volatile temporary drive in an Azure VM.
Temporary disk
Every VM contains a temporary disk, which is not a managed disk. The temporary disk provides short-term storage for applications and processes and is intended to only store data such as page or swap files. Data on the temporary disk may be > lost during a maintenance event event or when you redeploy a VM. On Azure Linux VMs, the temporary disk is /dev/sdb by default and on Windows VMs the temporary disk is D: by default. During a successful standard reboot of the VM, the data on the temporary disk will persist.

The amount of virtual memory is dynamically determined, loosely based around the table on the Ubuntu SwapSize FAQ.
You can set your desired size at any time, by writing to this file /etc/makeswap-on-azure/swap_size.
For example:
echo "1G" > /etc/makeswap-on-azure/swap_size
sudo systemctl restart makeswap-on-azure.service
The value can be something like:
- 8192K
- 2048M
- 1.5G
