Would it make sense to add these two new command-line options to "podman run"
--disable-subuid
--disable-subgid
so that it would easy to disable the use of
/usr/bin/newuidmap
/usr/bin/newgidmap
That would be handy when a user wants to run podman and be sure that
no subuids and subgids are used.
If you wonder about the terminology:
"rootless single mapping", I found it here:
[erik@laptop podman]$ grep "using rootless " ./pkg/rootless/rootless_linux.go
logrus.Warnf("using rootless single mapping into the namespace. This
might break some images. Check /etc/subuid and /etc/subgid for adding
sub*ids")
[erik@laptop podman]$
I could add a feature request to Github, if you think these options make sense.

Giuseppe would this be
possible, or are we already within the user
namespace before checking the options? If it is possible would we need
to set the inore-chown-errors option?
Most likely this would be implemented as a --security-opt nosuidmap.
I would not want to add it as a primary option.
