It looks like I've yet to find comprehensible instructions for rebuilding an initrd with either mkinitrd or dracut from within chroot. Using lsinitrd grepping initrds for the obsolete ESP ID I also grepped for nvme, and found mismatches: e.g. 6.0.12 module for 6.1.12 initrd, 6.1.12 module for 6.2.1 initrd. In too many cases, man pages to me are worthless due to absent or inadequate examples, dracut and mkinitrd notably included.
