 | kube-apiserver | /var/log/apiserver/  | 1 GB               | Kubernetes audit logs. See Kubernetes [Auditing documentation](https://kubernetes.io/docs/tasks/debug/debug-cluster/audit/) for mode information. |
 | kURL           | /var/lib/kurl/       | *10 GB *** | kURL data directory used to store utilities, system packages, and container images. This directory can be overridden with the flag `kurl-install-directory` (see [kURL Advanced Install Options](/docs/install-with-kurl/advanced-options)) |
 | Root Disk      | /                    | 100 GB             | Based on the aggregate requirements above and the fact that Kubernetes will start to reclaim space at 85% full disk, the minimum recommended root partition is 100 GB. See details above for each component. |
+| Temp storage   | /tmp                 | Variable           | In an airgapped installation, the temp directory `/tmp` is used to unpack the airgap image bundle before uploading to a registry.  The temp directory must be sized accordingly; we recommend twice the size of the airgap bundle size containing application images. The temp directory can be overridden by setting the `TMPDIR` environment variable before installing your application with `kots install`.  E.g. `TMPDIR=/mnt/bigdisk/tmp kubectl kots install APP_NAME --license-file PATH_TO_LICENSE --airgap-bundle PATH_TO_AIRGAP_BUNDLE` |
 
 ** This requirement depends on the size of the container images and the amount of ephemeral data used by your application containers.*
