Do you mean that 'mount -o remout,mod:/real_root=rw /your/aufs' returns
an error? What did it say?
:::
mount -o remount,mod:/real_root=rw /
mount: / not mounted already, or bad option
Are there any aufs messages left?
Yup .. didnt see them in the first place .. it's "aufs
parse_opts:540:mount[2056]: lookup failed /real_root (-2)
I think that is logical since neither /real_root nor /union exists or is
Currently I don't agree.
Will you try strace, and show me the output?
Sure, the strace log is attached.
