initramfs-live-boot: create /dev/console
Some kernels, for example linux-yocto 3.19 for qemux86, fail to execute /init in an initramfs unless there is already a /dev/console char device in the initramfs. Booting then fails with: Kernel panic - not syncing: /dev/console is missing or not a character device! Please ensure your rootfs is properly configured The panic itself comes from a linux-yocto specific patch to kernel_init_freeable in init/main.c, but even without it, that function will print an error when /dev/console is missing. The kernel's Documentation/initrd.txt also mentions creating that device. It remained unclear why this is not a problem on other machines. On intel-corei7-64 from meta-intel, something (the kernel?) creates /dev/console and /dev/[012] before transfering control to the init script. In that case, creating /dev/console in advance is not necessary, but does not cause any problem either. Signed-off-by: Patrick Ohly <> Signed-off-by: Richard Purdie <>
