Sounds like 'chroot' worked correctly in the above sequence.

I have no idea either.
This does not look like a bug report for the 'chroot' command from the
GNU Coreutils project however. It looks like a bug report against
'dracut'. As such there isn't anything that we can do about it here.
I think that is why no one else of the team responded. It didn't seem
like anything that anyone here could do anything about.
Also the chroot command line utility is simply a thin wrapper around
the chroot(2) kernel system call. It does whatever the kernel does.
Therefore I am going to close the bug in our ticket system. However
please do respond and add any further discussion. We will see it. If
something looks like a bug the ticket will be re-opened.
Bob
