 magic_rb | its how i do semi secret things like ips, dhcp ranges and wireguard configuration | 08:23:48 |
 hacker1024 | I am trying to build x86_64 packages on aarch64 using QEMU + binfmt_misc, but evaluation keeps failing.

 K900 (deprecated) | It's probably QEMU being QEMU | 11:54:31 |
| K900 (deprecated) | It's far from perfect | 11:54:35 |
| K900 (deprecated) | Especially when it comes to obscure x86 stuff | 11:54:40 |
| hacker1024 | To be honest, I'm not even sure that it's getting to the stage where it needs QEMU | 11:54:56 |
| hacker1024 | I don't know how to work out what process is crashing as the PID is only logged when it dies | 11:55:18 |
| hacker1024 | QEMU seems to be running normally outside of Hydra, I can launch x86_64 binaries without any issues | 11:56:07 |
| magic_rb | strace the hydra process and filter to execve | 12:34:23 |
| magic_rb | thatll tel you hacker1024: | 12:34:35 |
| hacker1024 | Thanks, that's a good idea | 12:35:06 |
| hacker1024 | I assume I'll need to enable fork tracing too | 12:35:17 |
| magic_rb | or the nix daemon, whatever is spawning the pid | 12:35:20 |
| magic_rb | yeah following forks may help, try without first to not overwhelm yourself with trace data | 12:35:51 |
