Making a
dracut -H KERNELVERSION
didn't succeed. Booting gives an error root=/dev/sda7 not found

I emerged dracut without any modules, because I just have a simple simple / - ext4 root gentoo installation.

My gentoo boots fine with an initramfs created by dracut without any useflags. I have a separate /usr so I needed to edit /etc/dracut.conf like this:
Code:

cat /etc/dracut.conf
add_dracutmodules+="usrmount"

This will create an initramfs in your /boot:
Code:

dracut /boot/initramfs-x86_64-3.2.5-gentoo.img 3.2.5-gentoo

Also, I use grub2 and it accepted only the initramfs created with the above syntax . ext4 is used for everything other than /boot.

My system never starts using a dracut.img, but stops at a dracut comandline with - as I remember - perhaps not correct wordings:
Code:

dracut Warning: unable to process initqueue
dracut Warning: /dev/sda7 not existing


This happens when creating with both methods:
dracut -H dracut.img KERNELVERSION
dracut dracut.img KERNELVERSION

just local and not, with usrmount or with both tried:
omit_dracutmodules+="btrfs xfs convertfs rpmversion net"
omit_dracutmodules+="usrmount"

or even with using
add_dracutmodules+="usrmount"

I tried with udev-171 and udev-181, I use kmod-5 instead of module-init-tools.

What I observe is when creating a dracut.img there are messages like
skipping 50-udev.rule ... alike
which skips rules not existing in my directory /lib/udev/rules.d. Which is why I think there is just too much hardcoded for fitting Fedora systems but not my ~unstable/experimental Gentoo system!?

[edit PS] I just found this Gentoo bug regarding kmod and dracut:

This was the kmod modules dependency bug!
kmod-9999 seems to have been patched for this!

I have these "skipping 50-udev.rule ... " alike messages, too. But, it seems they are harmless, since I don't have a problem.
Also, I dont have kmod installed. But I have "module-init-tools" installed. No problem for that, too.
