MODULES is only for the kernel to be *able* to load modules, not to *make* modules. If you use nvidia.ko, you must already have it. All the options can be compiled into the kernel; I had them like that: $ grep "BLK_DEV_BSG\\|DEVTMPFS\\|HOTPLUG\\|INOTIFY_USER\\|NET=\\|PROC_FS\\|SIGNALFD\\|SYSFS" /usr/src/linux/.config # CONFIG_SYSFS_DEPRECATED is not set CONFIG_HOTPLUG=y CONFIG_SIGNALFD=y CONFIG_BLK_DEV_BSG=y # CONFIG_BLK_DEV_BSGLIB is not set # CONFIG_MEMORY_HOTPLUG is not set CONFIG_HOTPLUG_CPU=y CONFIG_ARCH_ENABLE_MEMORY_HOTPLUG=y CONFIG_ACPI_HOTPLUG_CPU=y # CONFIG_HOTPLUG_PCI is not set CONFIG_NET=y CONFIG_INET=y CONFIG_WIRELESS_EXT_SYSFS=y CONFIG_DEVTMPFS=y CONFIG_DEVTMPFS_MOUNT=y # CONFIG_SCSI_PROC_FS is not set # CONFIG_ISCSI_BOOT_SYSFS is not set CONFIG_ETHERNET=y CONFIG_USB_USBNET=y CONFIG_RTC_INTF_SYSFS=y # CONFIG_DMI_SYSFS is not set CONFIG_INOTIFY_USER=y CONFIG_PROC_FS=y CONFIG_SYSFS=y

/dev should not be in /etc/fstab; but since you had this error:
> switch_root: failed to mount moving /dev to /sysroot/dev: Invaild argument > switch_root: forcing unmount of /dev > switch_root: failed to unlink dev: Directory not empty
I thought that it was maybe because you had /dev on fstab. Now we know it was because you didn't compile DEVTMPFS in your kernel.

The messages appear for sure; CONFIG_CHECK is defined in /usr/portage/eclass/linux-info.eclass, and if a config option is missing, a non-fatal warning will appear. If you have them, check your emerge logs: cat /var/log/portage/sys-fs\:udev-* | less You can look for the string: * Checking for suitable kernel configuration options... [ ok ] (Obviously that's in my case). You could also reemerge udev and dracut; if you haven't changed your kernel config options, they will complain loudly about it. I think that will solve the mistery; however, we will not know until you reboot and actually test it (after recompiling your kernel, of course).
