That was what I thought. I reproduced it and unfortunately I don't see a
standard way for avoiding this. I believe that the lines that case the problem
in checkroot.sh are the following:
if ! mount -n -o remount,$rootopts,$rootmode $fstabroot / 2>/dev/null
then
mount -n -o remount,$rootopts,$rootmode /
fi
The only fixes that I can think of are:
a) Ask initscripts' authors to add a check for already r/w root filesystem and
leave the root filesystem r/w.
b) On-the-fly change fstab to remove extra options.
I find (b) to be the easiest approach but I'm not sure that it won't cause
problems. Any thoughts on that?

Good point. I changed that.
p.s. I'm CC'ing this to the bug report address to keep track of the
conversation. It may be usefull for future reference.
