read-only. Yes, this does mean that the fsck code needs some improving, |
| 15 |
and potentially if it makes changes on a ro-mounted disk, the disk needs |
| 16 |
to be umounted & remounted, or a reboot needs to happen. Basically what |
| 17 |
we do for / now needs to extend to the other mountpoints as well. |

Err, I don't follow. How does mounting /var fill up the root partition? |

See my other notes on stuff in udev rules that require /var before they |
| 26 |
can complete successfully. |
