@os:matrix.flyingcircus.ioosnyx (he/him)

I had wanted to use replaceRuntimeDependencies in a system config to hotfix the latest glibc CVE, but unfortunately Hydra fails to evaluate it due to
error: access to absolute path '/nix/store/anlf335xlh41yjhm114swi87406mq5pw-glibc-2.38-44' is forbidden in restricted mode.

I guess there's a good reason why Hydra uses restricted mode and I better don't just patch evalSettings.restrictEval = false;?

@casey:hubns.netcasey ©there is probably a good reason, but back when i used hydra, i also patched that out for... reasons.16:01:28

I think the main reason was that h.n.o. is effectively evaluating untrusted Nix code and the devs wanted to have certain restrictions for that (e.g. being unable to fetch stuff from random URLs). I've seen it a few times that people patched it out in their overlays.

@os:matrix.flyingcircus.ioosnyx (he/him)The last time I looked (~1year ago), the effects of restricted mode weren't that greatly documented, neither in Nix nor what they cause in Hydra. So I'm always a bit wary about it.16:03:21
@ma27:nicht-so.sexyma27 not sure if much has changed about that...
But tests/functional/restricted.sh from the nix repo has a few test cases that may give a rough idea of what it does

@hacker1024:matrix.orghacker1024 How do you handle garbage collection when using an S3 store_uri? Is hydra-s3-backup-collect-garbage appropriate? It's made for the S3 backup plugin, which was made before Nix supported S3 natively and (as far as I can tell) is now redundant. 23:59:52
