In older versions of the dracut ebuild (<sys-kernel/dracut-036), DRACUT_MODULES was used to select which modules to install. In newer versions, DRACUT_MODULES is no longer used; instead, all modules are installed every time. That's why you see all the flags in parentheses: the flags have been removed from the ebuild, but they are effectively enabled now. Back to your logs, both of them say they cannot find the 'lvm2' module. This makes sense because 'lvm2' is not a valid dracut module. It seems like 034 just ignores this error, carrying on with building a possibly broken initramfs. As far as I can tell, the only way for that missing module message to show up is if you have that non-existing module listed in some dracut config file somewhere. You should check for stale files in /etc/dracut/dracut.conf.d, and in /usr/lib/dracut/dracut.conf.d. Remove any reference to the 'lvm2' module in the dracutmodules or add_dracutmodules variables. If you still can't get it working, post the output of dracut --debug foo.img somewhere please. Let's stick with dracut-041; I'm not interested in debugging an older version.
