Another problem here (I recent detected) when remounting / (aufs) won't 
work, ioctl32 emulation fail (seems that is not implemented)

:: Mounting Root Read-only                                               
/sbin/mount.aufs:plink.c:223: AUFS_CTL_PLINK_MAINT: Invalid argument

ioctl32(mount.aufs:1425): Unknown cmd fd(3) cmd(00004100){t:'A';sz:0} 
arg(00000002) on /
ioctl32(mount.aufs:1433): Unknown cmd fd(4) cmd(00004100){t:'A';sz:0} 
arg(09f24b80) on /

anyway is not an issue at least in this case.
