Dracut looks to replace the initramfs patchwork

Indeed. I have systems here that boot normally, systems here that need to
mount LVM, systems that mount LVM-atop-RAID, one bizarre system that has a
root filesystem on RAID-atop-LVM (!), a couple of systems whose RAID
arrays are assembled over the network block device, and one that never
actually mounts a root filesystem atop the rootfs but does all its work
from there.

Booting can be arbitrarily complicated: it must, no matter what, remain
possible to *replace* whatever standardized initramfs framework goes
upstream, because nothing will ever cope with all the utterly bizarre
corner cases.
