I think systemd is the one to learn now if you want to learn Linux. Maybe someone can make a Unix from Scratch for people more interested in the Unix philosophy than Linux per se.

SysVInit on Linux isn’t true Unix though as the way it abuses runlevels to start daemons was never intended by the original designers of init.
Yeah, people forget the degree to which sysvinit was hated at the time - "why are you forcing me to deal with an impenetrable forest of symlinks rather than simply hand-edit a couple of basic rc scripts?!?".
If the intention is to create a system that users can reason about, then sysvinit offers the worst of all possible worlds.
systemd is most certainly the most pragmatic service to learn, but if you're doing LFS to "learn" how a Linux system gets brought up, something lower-level may be a better idea to pick up.
All this stuff is versioned anyway so if the point is learning youe can still read an old version of the book and use old versions of the repos.
