… /etc/subgid This fix tries to address the issue raised in 39353 where docker crash when creating namespaces with UID in /etc/subuid and /etc/subgid. The issue was that, mapping to `/etc/sub[u,g]id` in docker does not allow numeric ID. This fix fixes the issue by probing other combinations (uid:groupname, username:gid, uid:gid) when normal username:groupname fails. This fix fixes 39353.
