Since I have enabled the ca-* related feature I think I have encountered a bug.
I filed it here
https://github.com/NixOS/nix/issues/4903
I think that when those ca-* flags are on sometimes nix tries to fetch unexisting cache path.
I’ve tried to enable -vvv to see what exactly was happening.
I’m waiting to test without the flags to see If the bug persists.
Unfortunately the bug itself is quite transient. It sometimes appears repeatedly, but I can’t isolate a minimum set of features to trigger it.
I finally managed to get my system to actually build something.
Sometimes I have to manually nix store delete something due to failed clean up from earlier builds, with I can live and cope with.
Though I do have some other problem now, I am not sure how to fix:
autogen> RPATH of binary /nix/store/kx284d6sd0i4dyfqv8ma26nhz1239swn-autogen-5.18.16-bin/bin/autogen contains a forbidden reference to /tmp/nix-build-autogen-5.18.16.drv-0/
error: builder for '/nix/store/nvyslzkbqqvasb2mr8pzcjyz558883zf-autogen-5.18.16.drv' failed with exit code 1
Also, using --keep-going I have already observed that there are sometimes hash mismatches, probably for FODs (it has to be for FODs, as I removed all substitutes).
@NobbZ Sounds like you are building with sandboxing disabled - this should be fixed by [staging] autogen: fix patchelf invocation to remove generic build path from rpath by r-burns · Pull Request #126557 · NixOS/nixpkgs · GitHub
This was indeed true, that machine still had the sandbox disabled.
Thanks for the hint! Will try again later, though currently it’s building the Linux kernel and as it’s already doing this for 2 hours, I prefer to not cancel this 
I’m now getting a build failure, 00:41 EST 2021-06-30

I have all 3 levels enabled.
Anyone used __contentAddressed = true with node2nix?
I’m using it with my mkDerivation but I’m not sure if it propagates to all the node dependencies. It seems to rebuild a lot every time.
__contentAddressed does not propagate at all. You need to set it for each derivation you want to be CA.

Is there a way to check that all dependent derivations are content addressed? Something like nix-store -q --tree result.
There’s no direct built-in way, but you can run something like
nix path-info --json --recursive /run/current-system | jq '.[] | select(.ca == null) | .path'

Does it propagate to buildInputs deps? With __contentAddressed = true it doesn’t seem to.
Will it do when I’ll use config.contentAddressedByDefault = true?
“doesnt propagate at all” means exactly that. If you have derivations A, B, and C, where A depends on B and B on C and B is CA, then A and C will still be IA.
Everything you build from that “instantiation” of nixpkgs will be CA, unless it already has an explicit __contentAddressed = false.

Is it possible to use config.contentAddressedByDefault = true with nix build to build 1 thing?
I wish I could test that without having to switch to content-addressed nix system-wide.
Unfortunately no. You can define an overlay that defines pkgsCA = import super.path { config.contentAddressedByDefault = true; }[^1] (I have something like that in my config).
[^1]: Hopefully there is a less ugly way to do that

I got this while trying to build rust code (with crate2nix). Should I report that somewhere?

Running nix-build --experimental-features 'ca-derivations ca-references' -A bash yields an error in my nix-daemon nix-daemon: src/libstore/sqlite.cc:92: nix::SQLiteStmt::Use::Use(nix::SQLiteStmt&): Assertion `stmt.stmt' failed..
Is this known or should I open an issue about it?
Edit: I think I know what is the reason for this. If you only activate experimental features for nix-build and not your nix-daemon. This should be handled more gracefully in my opinion.
@thufschmitt anything I can do to help or get help with my “hash mismatch” issue?
@bbigras This looks like [CA-drvs] Nix fails to remove directory trees · Issue #4858 · NixOS/nix · GitHub. Does your Nix version include Remove a possible existing store path when building CA derivations by thufschmitt · Pull Request #4928 · NixOS/nix · GitHub ? If it does then yes, please open an issue

@Sandro My guess is that your daemon didn’t have the ca-derivations experimental feature set when you started it, causing some internal inconsistency. I’ve opened #5017 to see what we can do about it as it’s at the very least a bad error message.

Actually this doesn’t explain the “hash mismatch”. Looking at the log snippets, it looks like you’re fetching stuff from a binary cache. So that might be related to Make the Nar hash non modulo by thufschmitt · Pull Request #4849 · NixOS/nix · GitHub (in which case there’s not much to do except rebuilding the cache)
I’m actually planning to build a NixOS Vm-expression where this can be reproduced by @thufschmitt (I had the same issue), but I got far too busy this week, so it may take a few more days
