Hmm... Those are nice, but can be easily built yourself with an off-the-shelf |
| 28 |
UPS. |

Hmm... add something to auto-shutdown the computer when a hotplug event occurs |
| 36 |
on any of the internal ports and remove support for unused ports from the |
| 37 |
kernel. |
| 38 |
|
| 39 |
I wonder how they'd keep a computer from initiating a shutdown procedure or |
| 40 |
causing a kernel panic when it looses (wireless) connection to another device |
| 41 |
that is unlikely to be moved when powered up? |
