bluefin-cli container returns zsh: permission denied: /var/spool/mail/$USER randomly

[johnrellim]

Describe the bug

When using the bluefin-cli container, it will randomly return zsh: permission denied: /var/spool/mail/$USER (username replaced with variable by me) in addition to whatever command was executed.

What did you expect to happen?

The command to be executed without extra output.

Output of rpm-ostree status

Extra information or context

This only happens in the bluefin-cli container. The host, ubuntu, and fedora containers all operate as expected.

The specific command does not matter, I've had it return this on everything from cd to ls to the rpm-ostree status command located in this issue.

<bluefin> # whoami
jrellim
zsh: permission denied: /var/spool/mail/jrellim

This has lasted throughout multiple container updates, OS updates, and re-downloading of the bluefin-cli container. It seems to happen at regular intervals, almost like something is attempting to access that location in the background. I don't have any mail programs installed, or anything I am aware of that would want to access that location.

Check what is being sourced by your zsh startup files.

This looks like an issue with a module trying to show if you have any mail in your prompt.

Zsh is definitely the shell (that we ship) that we have the least amount of coverage on right now.
