Re: [Ltib] Rootfs generated by LTIB

[Stuart Hughes]

Hi Yuri,

/bin/init is not required.  Normally I'd expect userspace to boot from
rootfs/sbin/init, which is usually a symlink to busybox:

$ find rootfs -name init
rootfs/sbin/init

How do you know if your ltib output is normal? I can't tell unless I see
it.

Please answer the question:
