Presumably you'd only want to remount it if it was mounted ro to |
| 22 |
start, since it sounds like openrc will be diverging from systemd |
| 23 |
behavior here. |

While it seems like a good idea I'm not sure how big an improvement it |
| 26 |
is in the larger scheme. We're worried about root accidentially |
| 27 |
modifying efivars, but we have no safeguards against root writing to |
| 28 |
/dev/sda, and the latter seems much more likely to cause harm, and is |
| 29 |
harder to fix. |
