How does it compare to install Arch linux without an installer? I remember that it took me a day or two of tinkering, when I did it for the first time (circa 2009) and I learned a lot. As of today, Arch remains my distro of choice.
The LFS book is quite thorough, so you technically only need to copy/paste commands, but you learn _a lot_ about Linux in the process. I highly recommend it to anyone interested in Linux. I did it once in college, and parts of BLFS IIRC, and it's one of the few memorable projects I got from my degree.
