Anaconda needs to copy /etc/nvme/hostnqn and /etc/nvme/hostid files, ensured to exist by INSTALLER-3679, to the freshly installed /mnt/sysimage (or before rpms are installed).

On RHEL 9, the nvme-cli %post scriptlets will generate new values if the files don't exist. However the values might be random-generated and need to be overwritten by values used in the earlier installation phases.
On Fedora, these scriptlets were intentionally removed and the code in INSTALLER-3679 is essential to have in place.
RHEL10 is still a mystery.

These files need to exist and have correct values before target initramfs is generated. The dracut nvmf module expects them to exist and silently fails if not present.
