1. I used to boot my kernel with genkernel-initramfs, but I must genarate the initramfs again by genkernel. when I change the kernel vernsion.
2. I have the '/' partition created with lvm, when I use genkernel to make the kernel and initramfs( with option --lvm ), the error "block device /dev/mapper/vg-gentoo_root is not a valid root device" show up. kernel version 3.2.2
3. I try to emerge dracut-018 to create my initramfs, but I use the USE DRACUT_MODULES="lvm", which try to emerge device-mapper and* conflict with lvm2. I am pullzed.
thx in advance.

You need LVM >= 2.02.33 for dracut 018. Which version do you have?
Also, do you have device-mapper enabled in /etc/make.conf?
Regards.

I miss the USE device-mapper, that is my fault. now I install the dracut completely.
Thank you!

Do you have "dolvm" in the kernel boot options? That's needed.
