Mount points during SLES 11 SP2 installation

Hi,

I have observed that several mount points are created /mounts/{mp_0001 to mp_0007} when installing SLES 11 SP2 from hard disk. But in some systems , the mount point number is starting from “mp_0002”. I would like to understand on what basis the autoyast installer creates those mount points?.

Thanks,
Prakash
