If you mean that your /usr/include/fcntl.h (or its sub-included files)
doesn't define O_CLOEXEC, then I am afraid it is violating some
standards and I cannot support such system.
I thought you are using glibc since your cross-compiler is gcc, isn't
it?

Actually it is not same.
Your previous post showed
aufs on / ... br:/tmp/rw=rw:/tmp/sqfsh=rr)
The difference is the branch path in the aufs entry. That is why I asked
about the module parameter 'brs'.

Ok, that is correct.

Ok, that is correct too.

Why do you think /proc/mount is incorrect.
It is absolutely correct since you have run switch_root, right?
