           Summary: /dev/console and /dev/null have to be created on udev
                    based systems also
           Product: buildroot
           Version: 2011.08
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: minor
          Priority: P5
         Component: Other
        AssignedTo: unassigned at buildroot.uclibc.org
        ReportedBy: fenixk19 at mail.ru
                CC: buildroot at uclibc.org
   Estimated Hours: 0.0


Now buildroot have two device tables - device_table.txt used in static and
dynamic /dev variants, and device_table_dev.txt, that is used only in static.

But devices /dev/console and /dev/null have to be static created for both types
of /dev filesystem.
So, probably, it would be good to move /dev/null and /dev/console definition
from device_table_dev.txt to device_table.txt?

No. Our udev and mdev support relies on the devtmpfs filesystem to be enabled
in the kernel and mounted at boot time by the kernel. Buildroot ensures that
this is the case for kernels that it builds (see the following code in
linux/linux.mk), but if you build your kernel outside of Buildroot, it is up to
you to enable those options as well.

        $(if $(BR2_ROOTFS_DEVICE_CREATION_STATIC),,
                $(call KCONFIG_ENABLE_OPT,CONFIG_DEVTMPFS,$(@D)/.config)
                $(call KCONFIG_ENABLE_OPT,CONFIG_DEVTMPFS_MOUNT,$(@D)/.config))

So you must enabled CONFIG_DEVTMPFS and CONFIG_DEVTMPFS_MOUNT in your kernel.
