The modules get defined by the DRACUT_MODULES variable, which is use-expanded. The options are configured in /etc/dracut.conf, but I believe there are some command line options not configurable. >> I didn't use an initramfs for my first years using Gentoo.

I see it the other way around: you ensure that your initramfs is in sync with your system. In other words: the initramfs contains a subset of your normal installation. That is why it makes redundant /lib, /sbin and /bin. Regards. -- Canek Peláez Valdés Posgrado en Ciencia e Ingeniería de la Computación Universidad Nacional Autónoma de México
