+// Read-only disk creation is disabled pending a propolis fix. To re-enable:
+// 1. Uncomment CheckboxField import and JSX in this file
+// 2. Uncomment CheckboxField JSX in app/forms/instance-create.tsx
+// 3. Use `values.bootDiskReadOnly` instead of hardcoded `false` in instance-create.tsx getBootDisk
+// 4. Use `source.readOnly` instead of hardcoded `false` in the onSubmit handler below
+// 5. Unskip e2e tests in test/e2e/disks.e2e.ts and test/e2e/instance-create.e2e.ts
