Yes, I understood ... thanks.

Aside from that a more general question:

Does it it any way help to have a *small* (= as small as possible)
initramfs?

Maybe on embedded systems but on the big multi-GB-ram-machines we use it
doesn't make much difference, right?

I ask because in all my reorganizing furor I also thought that now with
btrfs only I could get rid of "lvm mdraid" as dracut-modules. I can try
... ;-) (don't call me "ricer")

Additional in this context: does it make a noticeable difference which
"Kernel compression mode" you choose? I assume it is again an issue for
systems with (a) small boot-partitions and/or (b) slower CPUs to select
something special here.

I checked and see that I use LZ4 anyway already ... seems to be the
fastest to unpack as far as I understand the help text.

And then, who writes the howto condensed out of this thread? ;-)
Much to learn and understand as always, I appreciate it a lot.
