I don't think systemd requires 10 daemons for network config, isn't it only systemd-resolvd for DNS, systemd-networkd for actual network, and systemd-timesyncd for NTP?

If you only mean to say that you replace 3 bits of systemd then it would be good to say that, and to say which bits of systemd it replaces.

A lot of distros do not even use those systemd services, for example ubuntu does not use systemd-networkd by default.

I read "it weights only 1/100 of SystemD" as if it compared systemd to connman directly.
