Sometimes you might need to look up the kernel version of a past image. This is useful if you have a regression in a new kernel and want to find out what image has what kernel. Each container has an `ostree.linux` label that tells you what the version of the kernel in that image is. We use the `skopeo` tool to inspect it:

```
skopeo inspect docker://ghcr.io/ublue-os/bazzite:39-20240210 | grep ostree.linux

```

This returns:

```
"ostree.linux": "6.7.3-200.fc39.x86_64",

```
