The real question is, when will this joke finally get old? Like is it really still funny to make joke after literally every thread about SystemD has made this joke for 10+ years.

Btw, it already exists and its called ParticalOS:

systemd-antivirusd*

I mean. It doesn't use RPMs (directly), but systemd-sysupdate and systemd-sysext do cover that ground. Though the vision seems to be somewhat coarser than traditional packages.
