## Testing
- [ ] Added/updated automated tests
- [x] QA'd all new/changed functionality manually
Was able to reproduce by enrolling a Ubuntu 25.10 host and mounting /
onto a different path like this:
```bash
sudo mkdir -p /tmp/snap.rootfs_TESTING
sudo mount --bind / /tmp/snap.rootfs_TESTING
```
Then, refetched vitals and saw the total disk space doubled:

/>
With the fix applied on this branch, refetched again and saw the correct
total disk space:

/>
