I've been using the systemd timer that comes with util-linux upstream without |
| 18 |
modification, which runs fstrim weekly. That seems to work well, but to be |
| 19 |
quite honest, I wouldn't know how to tell. Sometimes I wasn't even sure it |
| 20 |
ran, so I would run it manually, and it always finished nigh-instantaneously. |

Before that, I used the discard mount option, but apparently that's only a good |
| 23 |
idea with high-end SSDs (not that I noticed much of a difference in everyday |
| 24 |
usage). |
