Well during package installation done by the installer, some packages, usually the ones that installs daemons/services, populates /etc/shadow. On Archlinux, after creating a minimal rootfs, shadow file is containing: bin:x:14871:::::: daemon:x:14871:::::: mail:x:14871:::::: ftp:x:14871:::::: http:x:14871:::::: uuidd:x:14871:::::: dbus:x:14871:::::: nobody:x:14871:::::: systemd-journal-gateway:x:14871:::::: systemd-timesync:x:14871:::::: systemd-network:x:14871:::::: systemd-bus-proxy:x:14871:::::: > >> BTW, I don't know if recovering when /etc/ has been deleted is >> possible even if systemd-firstboot will restore a couple of conf >> files... > > Depending on your distribution, it is. Just out of curiosity, which distros are supposed to support that ?
