Yes. Uruk is downstream from Trisquel Flidas which is downstream from Ubuntu Xenial Xeres which is downstream from Debian Jessie so it uses systemd.
If you are looking for systemd-free alternatives, you might consider devuan, freeslack (no 32 bit support, but 64 bit looks good), and/or hyperbola[1]. [1]https://trisquel.info/en/forum/i-found-new-libre-distro-you-all-might-be-interested
