[gentoo-user] Dracut and how to specify names

[Dale]

Howdy,

I'm trying to rebuild a kernel to include new options, see other
thread.  I got the kernel built but dracut is giving me grief.  I hate
that thing and when a previous way that worked no longer works, it
doesn't help me like it any more.  Still, it is what it is even if I
don't like it.  I read the man page, the Gentoo wiki and tried different
methods but it just refuses to build a init thingy that I need.  It
either fails right away or gets to the end and errors out without
completing.

I name my kernels and such this way:

root@fireball /usr/src/linux # ls -al /boot/kernel*
-rw-r--r-- 1 root root 7061552 Oct 14  2018 /boot/kernel-4.18.12-1
-rw-r--r-- 1 root root 7082032 May 15  2019 /boot/kernel-4.19.40-1
-rw-r--r-- 1 root root 7102512 Jan  2 19:46 /boot/kernel-4.19.40-2
-rw-r--r-- 1 root root 5858496 Jun 17  2016 /boot/kernel-4.5.2-1
root@fireball /usr/src/linux #

I copy the kernels from the /usr/src/linux directory by hand as I've
always done.  I name them starting with kernel and then add the kernel
version with a sequence number on the end.  In the past, I've made it to
-4 before getting what I need.  Right now, I'm working on 4.19.40-2 and
building a init thingy for it.  This is how the init thingys end up, in
the past anyway:


root@fireball /usr/src/linux # ls -al /boot/initramfs*
-rw------- 1 root root 7752134 Oct 15  2018 /boot/initramfs-4.18.12-1.img
-rw------- 1 root root 8560993 May 15  2019 /boot/initramfs-4.19.40-1.img
-rw------- 1 root root 5377395 May 20  2016 /boot/initramfs-4.5.2-1.img
root@fireball /usr/src/linux #


What I need, the proper command with options to tell dracut I want to
build a init thingy for 4.19.40-2.  I've tried many different ways but
none of them work.  This includes commands I've used in the past that
did work.  If I have to specify the init thingy name and the location of
the kernel modules directory, that's fine.  I keep commands like this in
a file to refer back to because I do tend to forget specifics but in
this case, it seems dracut changed something.  Previous commands are not
working. 

Does anyone know how to accomplish this task?  Hopefully something that
will work even if dracut changes something with its defaults.  I figure
if I tell it all it needs to know, then it should work even if dracut
changes the default method.  I just can't seem to figure out what method
to use here.  Maybe I'm missing a option or something. 

Thanks much. 

Dale
