Is there some other event that will cause all filesystems to be |
| 8 |
remounted read-only or unmounted before shutdown? |

You definitely will want to either unmount or remount readonly all |
| 11 |
filesystems prior to rebooting. I don't think the kernel guarantees |
| 12 |
that this will happen (I'd have to look at it). Just doing a sync |
| 13 |
before poweroff doesn't seem ideal - if nothing else it will leave |
| 14 |
filesystems marked as dirty and likely force fscks on the next boot |
| 15 |
(or at least it should - if it doesn't that is another opportunity for |
| 16 |
data loss). |

There are different ways of accomplishing this of course, but you |
| 19 |
really want to have everything read-only in the end. |
