Yes, I am certain that systemd uses this file to set the system hostname. It does *not* read /etc/conf.d/hostname, which is the main point here. > Because I'm on systemd here, working fine as far as can be observed, and > I don't have /etc/hostname. > > [after googling and checking manpages] > > Seems it's (semi-?)optional.

Nobody actually does this, except you and a few other Gentoo people. Most kernels in the wild are compiled by distro maintainers, who have no idea what you want to call your computer. Setting the hostname via a text file in /etc is a lot simpler than re-configuring a kernel. > So it seems systemd works just fine without /etc/hostname, certainly so > if it's set elsewhere, like say via kconfig option. I never said /etc/hostname was necessary for operation of systemd. It *is* the way that normal people set their hostname for a system that doesn't get configured via DHCP or some dynamic method.
