> These generally follow the unix philosophy of doing one thing and doing it well and are almost all completely optional. So I can take just systemd-networkd or just systemd-resolvd and install it on a FreeBSD box? Just because these are different binaries does not make them 'separate'. All the things in the systemd code base are tightly coupled together. That is the opposite of the Unix philosophy.
