Hmm, I suppose it's possible that the host might matter as well. I'm
running podman-5.7.0-1.fc43.x86_64 and the following commands (the
`ls` is typed in by me and followed by <enter>`):

```
% podman run --rm --tty --interactive  fedora:43-s390x  /usr/bin/bash
WARNING: image platform (linux/s390x) does not match the expected
platform (linux/amd64)
ls
afs
bin
boot
dev
etc
home
lib
lib64
media
mnt
opt
proc
root
run
sbin
srv
sys
tmp
usr
var


```

vs

```
% podman run --rm --tty --interactive fedora:42-s390x  /usr/bin/bash
WARNING: image platform (linux/s390x) does not match the expected
platform (linux/amd64)
[root@9f03a96f897c /]# ls

root  run  sbin  srv  sys  tmp  usr  var
[root@9f03a96f897c /]#
```
