Yes.
But I noticed it won't work for you.
Because you are over-mouning /bin, the mount command
("remount,mod:/bin=ro") at shutdown-time will not find "/bin" branch
which should be set readonly.
If you don't want to upgrade and re-compile your aufs, you need to
separate these names by tricky binding or something.
For example,
(boot)
mkdir /sysroot/aufs/bin
mount -t aufs -o xino=/sysroot/tmp/xino,br:/sysroot/bin:/sysroot/.mount/bin \
aufs /sysroot/aufs/bin
mount -o bind /sysroot/aufs/bin /sysroot/bin
(shutdown)
umount /sysroot/bin
# you may specify $PATH
mount -o remount,ro,mod:/bin=ro /aufs/bin
