clamav up until version 99 had no systemd dependencies, it seems it does now.
Artix rebuilds the pkg and has libeudev as a dependency
Here is ver.101 dependencies from void

I can deduce and suspect that substituting libsystemd with eudev in obarun it might work, I just think this is getting a little crazy, or I could install the artix pkg and dd the libeudev dependency as I believe it is incorporated into obarun/eudev

Are these people making linux pkgs or are they making systemd packages? The way void built the package it makes me wonder, unless what is inside libeudev is covered by void's dependencies.
