| 13:29:57 |
| matthewcroughan | deprecated? | 13:29:59 |
| matthewcroughan | literalExpression would still string interpolate if I put a ${pkgs.zstd} though right? | 13:30:51 |
| matthewcroughan | It'll still take the string context from it? | 13:30:59 |
| matthewcroughan | * It'll still take the string context from it and substitute a nix store path? | 13:31:05 |
| lassulus | well I'm old I can't keep up with all the deprecations :D | 13:31:31 |
| matthewcroughan | I'm young and neither can I | 13:31:41 |
| matthewcroughan | But yes, I don't know how to provide an example that escapes the ${}, literalExpression still won't do that | 13:32:25 |
| matthewcroughan | I'm unsure if the '' ends up getting rendered | 13:32:50 |

| matthewcroughan | yeah that looks to be the way | 13:37:47 |
| lassulus | maybe just escape the ${ then? | 13:38:10 |
| matthewcroughan | Yeah, that's the way | 13:38:26 |
| matthewcroughan | literalExpression "''${foo}" is the way | 13:38:40 |
| lassulus | in " ${ is escaped with \ | 13:40:00 |
| lassulus | but in '' this would be correct | 13:40:24 |
| matthewcroughan | Huzzah! I have had disko produce a raspberry pi 4 bootable image for me :) | 14:13:27 |
| matthewcroughan | with bcachefs as the FS | 14:13:41 |
| matthewcroughan | that took foreeeeever | 14:13:46 |

| lassulus | forever in writing the code or forever in running it? | 14:14:23 |
| matthewcroughan | writing code | 14:14:28 |
| matthewcroughan | Because the Pi is so weird | 14:14:37 |
| matthewcroughan | pi3 would require even more changes to do this, because it doesn't support gpt only | 14:14:48 |
| matthewcroughan | And that's where we were last time I came in here asking about Pi booting | 14:15:00 |

| matthewcroughan | something like this does everything | 14:15:59 |
| matthewcroughan | now the only remaining problem is resize on first boot | 14:16:18 |
