That's what your script/program does. It doesn't matter exactly what
the commands used are, but that's their overall intent: to get rid of
the original root device and give you another one. How do you
expect that to happen while the client daemons are running on the old
root and have stuff open there?

Whatever one you are using!  I don't mind if it's a script (which I
originally saw) or program (you later posted a linuxrc executable
source code) - for a program you'd want to run it under strace to
get good debugging info.

But it doesn't.

It doesn't matter. Please address the concern. When you've done that we
can look closely at yur programs.
