There's also 'uptime', which is installed optionally if you build 
coreutils with './configure --enable-install-program=uptime'. Ordinarly, 
though, I think people use procps-ng for 'uptime'. The procps-ng 
'uptime' links libsystemd the same way that coreutils 'uptime' does, 
i.e., it's an essential dependency.

And yes, these are the only coreutils programs for which libsystemd is 
required, unless you configure with --enable-single-binary in which case 
the 'coreutils' single-binary command requires libsystemd.
