What issue are you seeing?

When doing an appshot in the Codex App, I get the "Unable to attach appshot" error. From what I can tell, it's happening at this point in the log:

What steps can reproduce the bug?

I've isolated the issue to having procps installed on in my nix environment, leading to having the non-default ps command on PATH.

Removing the package seems to resolve the issue and I'm now able to attach app snapshots as expected.

What is the expected behavior?

The Codex App should ideally handle this situation better and either also allow for the ps utility from procps as well or explicitly use the command at /bin/ps.
