What issue are you seeing?

bwrap sandbox doesn't work due to the following error. It fails and then will ask users for permissions to run commands that could be run inside the sandbox.

codex -c 'features.use_linux_sandbox_bwrap=true'

› can you echo hello to test.txt
bwrap: Can't mkdir /home/$USER: No such file or directory

I believe the issue is that my home dir is symlinked to some NFS dir.

> realpath /home/$USER
/mnt/.../.../user/home/$USER

A min repro is

> bwrap --die-with-parent --ro-bind / / --bind /home/$USER /home/$USER bash -lc 'ls /home/$USER'
bwrap: Can't mkdir /home/$USER: No such file or directory

> bwrap --die-with-parent --ro-bind / / --bind /home/$USER /mnt/.../user/home/$USER bash -lc 'ls /home/$USER'
(this works)

So this could be fixed by using the realpath ofDEST in --bind.

What steps can reproduce the bug?

see above

What is the expected behavior?
