I'd be inclined to say `getent' would probably make it less portable than
hardcoding /etc/passwd. Nevertheless, it's actually available in some form on
most BSDs and Solaris as well, at least, which should cover most use cases. My
main concern would be limited/embedded environments (busybox/etc) rather than
other Unices.
