Doesn't eval in chroot store.

[kevincox]

The docs around chroot stores are basically non-existant so I may be doing it wrong but it appears as though the following should work but doesn't. It is also possible that the bug is in nix not naersk.

% nix-build --eval-store /tmp/store --store /tmp/store --show-trace
error: Naersk requires Cargo.lock to be available in root. Check that it is not in .gitignore and stage it when using git to filter sources (which flakes does)

--show-trace output

This was performed in a clean checkout of https://gitlab.com/kevincox/feed-test but seems to happen on all naersk repos.

I also tried with just --store and just --eval-store and got the same error.

The source does appear to be in the chroot store so I don't know what is going wrong.

[kevincox]

It is worth noting that running the build once outside of the chroot store makes the problem go away. Presumably because it is accidentally reading the sources from the host store.

[kevincox]

This can be worked around by passing --eval-store local along with --store /whatever.
