im on ~amd64 packages ok so when i build an initramfs with gentoo-next my ps/22 keyboard is not recognized by libinput and evdev both and doesnt work in xorg. Also a USB keyboard and mouse would have to be unplugged and replugged in before they would be recognized by the system after a reboot ok, so it took me a few days to pin down the cause of this, im fairly sure its the early loading of udev (eudev) thats causing all these things to not get loaded properly. switching to genkernel (not genkernel-next) creates an initramfs that causes these problems not to happen. i don't know if this is a bug report with problems that need fixed, or if its because eudev gets loaded too early by the initramfs and its a feature request to optionally remove genkernel-next's ability to load udev into the initramfs. If you can already do that i'm not sure how.
Package removed.
