Notes
| Author | Note |
|---|---|
| Priority reason: Non-default and improbable configuration | |
| mdeslaur | This is only an issue when hwclock was modified by the administrator to be setuid root, which should never be done. Ubuntu packages are not shipped with the setuid bit set. To prevent misconfiguration, version 2.27 now prevent it from being run setuid. |
