 tomberek | Looking at Figure 5.2 from thesis the supported types are regular(executable and normal), Symlink, Directory. I believe this is still true: https://github.com/NixOS/nix/blob/master/src/libutil/archive.cc#L202-L219 (btw: considering how long ago it was, the NAR format is still on the original version 1 ! A good testament to keeping it simple) | 03:41:31 |
 tpw_rules | i'm just wondering if it's a problem if we potentially remove a hardlink a derivation has made itself. i am not sure they are distinguishable from ones made by --optimise | 03:42:32 |
| tpw_rules | and i guess not, if nar does not convey that information | 03:43:00 |
| tpw_rules | i will do some testing and submit a PR tomorrow night | 03:43:19 |
| tomberek | Sounds reasonable | 03:47:20 |
 afontain | So the point is to have two copies instead of one, until it gets optimized? | 10:01:22 |
 atemu12 | It's to always have two copies in the CPIO, no matter the stateful optimisation. | 12:44:16 |
| afontain | sounds good | 12:49:32 |

| tpw_rules | bah, why is the initrd still not reproducible. what does that column mean? | 04:51:16 |
| atemu12 | tpw_rules: looks like the hardlink issue? Te PR that fixes it is still in staging I believe | 09:26:26 |

 raboof | hmm https://nixpk.gs/pr-tracker.html?pr=157235 suggests it should've made it by now | 09:41:59 |
| tpw_rules | the commit hash that page says it used has it | 18:35:03 |
| tpw_rules | as far as i can tell | 18:35:33 |
| tpw_rules | i was able to get a reproducible build for whatever hydra built on 4.15 with ext4 and 5.4 with zfs. i don't know what the column diffoscope is describing doesn't match is. inode number? | 23:27:28 |
| tpw_rules | (and on both systems pre and post store optimization) | 23:27:55 |
| tpw_rules | "nlink" apparently | 23:35:02 |
| atemu12 | So the patch didn't do anything? That's surprising. | 23:36:24 |
| tpw_rules | well it appears the formerly hardlinked files are not removed from the archive now? but the cpio directory entries are still different | 23:37:19 |
| tpw_rules | it works for me... | 23:37:21 |
