 helle (just a stray cat girl) | uh, presubmitting as part of the link that is | 10:47:35 |
| helle (just a stray cat girl) | like the current link submits everything | 10:47:46 |
| helle (just a stray cat girl) | which breaks things | 10:47:49 |
| helle (just a stray cat girl) | otoh, if it is our server that breaks, "just" fix the server side of it? | 10:48:22 |
 Atemu | A while back, I found nothing in this direction and gave up because even with gross scripts, you can't get other clients that bring their own nix client (i.e. colmena, nixpkgs-review to not do remote builds by default. | 11:53:04 |

 Sofie 🏳️⚧️ (she/her) | or nix portable? | 12:50:25 |

 neobrain | Is it expected that the disk space reported by nix store gc is much higher than the actual savings I see when comparing (btrfs filesystem) df / before/after the gc run? | 23:23:42 |
| neobrain | One scenario I tested makes the former report 2.4 GiB savings when it was actually only 1 GiB, for example | 23:24:14 |
 raitobezarius | btrfs is CoW | 23:24:30 |
| raitobezarius | lix has no way to know better than summing up sizes of things being deleted | 23:24:43 |
| raitobezarius | * btrfs is CoW & compressed | 23:24:48 |
| raitobezarius | * btrfs is CoW & [inline] compressed | 23:24:53 |
| raitobezarius | but btrfs knows much better than us | 23:25:06 |
| neobrain | oh interesting. Compression makes a lot of sense. How does CoW influence this? | 23:25:46 |
| raitobezarius | if 2 inodes are CoWed and lix removes them [while they're not hardlinked], lix will count them twice but btrfs will deduce once I suppose? | 23:26:26 |
| raitobezarius | if the CoW is transparent via reflinking, maybe we could know but I don't know off my head whether this is the case | 23:27:15 |
| neobrain | That's deduplication, right? I assumed that only happened after user request | 23:27:27 |
| neobrain | * That's deduplication, right? I assumed that only happened after user request since btrfs doesn't do it automatically | 23:27:56 |
| raitobezarius | indeed, if reflinkage only happens upon demand, then, CoW doesn't influence this | 23:28:01 |
