All, |

I recently discovered laptop-mode-tools and it does replace advantageously the |
| 4 |
scripts I had written to respond to acpi events. And it does much more! |
| 5 |
|
| 6 |
One thing it does not do (nor were my scripts) is turn off things like |
| 7 |
updatedb when running on battery. I looked into that and thought about the |
| 8 |
various options and here's the result: |
| 9 |
|
| 10 |
- One could just move the slocate script from and in /etc/cron.daily to |
| 11 |
control it running or not. The problem with that approach is that the script |
| 12 |
needs to be saved somewhere and then moved (or linked) when it is needed. |
| 13 |
Moreover, if people want to run it weekly instead of daily, then the moving |
| 14 |
needs to be changed. |
| 15 |
|
| 16 |
- One could remove the slocate script from /etc/cron.daily (or wherever it is) |
| 17 |
and have a line in the crontab file. This has very similar limitations to |
| 18 |
the method above. |
| 19 |
|
| 20 |
- One could have laptop-mode-tools write something like "updatedb=[off|on]" in |
| 21 |
some state file (let's say in /var/state) and have the slocate script source |
| 22 |
that state file and run or not updatedb based on the value of the defined |
| 23 |
variable. This would not have the above limitations and could be applied to |
| 24 |
all the cron jobs. However, this would need modifying system scripts, |
| 25 |
therefore introducing more work at every update of these. |
| 26 |
|
| 27 |
I do think that the final method is the way to go to solve that problem and |
| 28 |
would be interested in developing/experimenting that. |
| 29 |
|

Has anybody done anything like that? Is that something that could be |
| 31 |
integrated in gentoo at some stage? Do people have |
| 32 |
suggestions/comments/criticisms, etc.? |
| 33 |

Cheers, |
