I've only one aufs:
none / aufs
rw,xino=/etfw_changes/.aufs.xino,br:/etfw_changes=rw:/cdrom/confs=ro:/cdrom/tmpdir/15=ro:/cdrom/tmpdir/14=ro:/cdrom/tmpdir/13=ro:/cdrom/tmpdir/12=ro:/cdrom/tmpdir/11=ro:/cdrom/tmpdir/10=ro:/cdrom/tmpdir/9=ro:/cdrom/tmpdir/8=ro:/cdrom/tmpdir/7=ro:/cdrom/tmpdir/6=ro:/cdrom/tmpdir/5=ro:/cdrom/tmpdir/4=ro:/cdrom/tmpdir/3=ro:/cdrom/tmpdir/2=ro:/cdrom/tmpdir/1=ro:/etfw=ro
0 0
the others that you see (like this:
none /srv/webmin/squid aufs
rw,xino=/etfw_changes/.aufs.xino,br:/etfw_changes=rw:/cdrom/confs=ro:/cdrom/tmpdir/15=ro:/cdrom/tmpdir/14=ro:/cdrom/tmpdir/13=ro:/cdrom/tmpdir/12=ro:/cdrom/tmpdir/11=ro:/cdrom/tmpdir/10=ro:/cdrom/tmpdir/9=ro:/cdrom/tmpdir/8=ro:/cdrom/tmpdir/7=ro:/cdrom/tmpdir/6=ro:/cdrom/tmpdir/5=ro:/cdrom/tmpdir/4=ro:/cdrom/tmpdir/3=ro:/cdrom/tmpdir/2=ro:/cdrom/tmpdir/1=ro:/etfw=ro
0 0
)
Are mount binded. Without mount bounded the /proc/mounts is:

I run linuxrc, line a line, and the bound mount is hidden after this line:
pivot_root /mnt/aufs /mnt/aufs/filesystem/initrd
After this the linuxrc has two more lines:
exec < filesystem/dev/console &> filesystem/dev/console
exec /filesystem/lib/ld-linux.so.2 --library-path /filesystem/lib
filesystem/initrd/bin/chroot filesystem /sbin/init
