passwd, shadow, group, gshadow etc. can be managed via nss - e.g. system default accounts can be specified using nss_altfiles, rather than in /etc/. Thus despite having default accounts, these files can be missing on disk and thus should be opened with O_CREATE whenever they are attempted to be opened in O_RDWR modes.
