 hexa | the default is 100 | 00:59:20 |
 c4lliope | I need a method of exploring the closures to see why | 00:59:22 |
| hexa | nix why-depends | 00:59:47 |
| hexa | or nix-tree | 01:00:12 |
| c4lliope | Yeah! And I get the idea behind the configLimit but with nix-collect-garbage --old, there is only one configuration at all. | 01:00:27 |
| hexa | ok, so your system closures are generally anchored by gcroots | 01:01:07 |
| hexa | they are in /nix/var/nix/gcroots | 01:01:18 |
| hexa | well, not only your system closures | 01:01:32 |
| hexa | also result-symlinks that are still floating around | 01:01:53 |
| c4lliope | oh dang there are so many gcroots. so damn many | 01:03:03 |
| c4lliope | I'm on generation 1000+ so I should have learned this ages ago, thank you!
I can already see the difference, should plug in before the fan takes off. | 01:06:57 |
| hexa | haha, enjoy | 01:08:15 |
| hexa | 2005 here 😄 | 01:08:38 |
| c4lliope | eh, configurationLimit=8 helped some but not too much. still a few libreoffices hanging around. I'll run through nix-tree, thanks for the quick help! | 01:12:05 |
| c4lliope | ahhhhhhh
libreoffice does not appear at all in sudo nix-tree. | 01:16:10 |
| c4lliope | nor cef. | 01:16:28 |
| hexa | nix-tree by default loads the current system closure | 01:17:36 |
| c4lliope | I see... fan intensifies | 01:20:54 |
| c4lliope | oh dang, I realize my current profile is 17 GB and my store is 186 GB | 01:22:49 |
| c4lliope | I really assumed the gc would handle this. More to learn, yay. | 01:23:14 |
| c4lliope | I've always been fascinated by these mechanisms so this is amazing. | 01:23:49 |
| c4lliope | oh it's all dev shells:

| hexa | persistent tmp? 😲 | 01:36:15 |
| c4lliope | uh no...
there are 1664 tmp folders and the oldest is 2025-07-20
I prefix nearly all my commands with nd, nix develop | 01:40:16 |
| hexa | https://github.com/NixOS/nix/issues/5207 | 01:41:13 |
| hexa | lix has this fixed | 01:41:23 |
| hexa | apparently nix 2.30.0 tries to keep deleting | 01:42:20 |
| c4lliope | dude you're a real paladin here, I feel like a wolf-child stumbling into civilization. | 01:42:22 |
| c4lliope | boot.tmp.cleanOnBoot = true; - see ya on the other side. | 01:46:09 |
| c4lliope | sure, the tmp files are cleaned up, no real difference.
I did find a reference in a random gcroot to libreoffice -
of the hundreds of gcroots here, how do I responsibly erase a bunch? | 01:52:18 |
