| Mic92 | hexa (signing key rotation when): ^ was this ue? | 10:17:18 |
| Mic92 | * hexa (signing key rotation when): ^ was this you? | 10:17:23 |
| hexa (signing key rotation when) | yep | 10:17:23 |
| hexa (signing key rotation when) | running fast-nix-gc instead | 10:17:44 |
| Mic92 | alright | 10:17:59 |
| hexa (signing key rotation when) | ehhh, the queue-runner came back up | 10:20:02 |
| hexa (signing key rotation when) | oh, socket activation | 10:20:18 |
| Mic92 | oh my god: [root@mimas:~]# du -sh /nix/var/nix/db/db.sqlite
16G /nix/var/nix/db/db.sqlite

| Mic92 | I was wondering why nix-fast-gc was taking so long in single-threaded mode | 10:29:32 |
| hexa (signing key rotation when) | is this already a size where behaviors get pathological? :P | 10:29:33 |
| Mic92 | no | 10:29:41 |
| Mic92 | but you need the RAM | 10:29:45 |
| Mic92 | I tried to make it efficient | 10:29:49 |
| Mic92 | should be fine in this case | 10:29:53 |
| hexa (signing key rotation when) | silly me tried --delete-old | 10:30:11 |
| hexa (signing key rotation when) | will go for --ensure-free next time round | 10:30:16 |
| Mic92 | it will read the sqlite db into memory in any case. | 10:36:09 |

| hexa (signing key rotation when) | do we have an idea, why it loaded multiple hundred GB into its nix store? | 10:40:56 |
