Grub menu entry without "root=" in SLES11SP2 machine

[Chaitanya Gotkhindikar]

Hello,

I am trying to write a script that parse /boot/grub/menu.lst. On SLES11 SP2 installed machine 

I observed that no "root=<device>" entry specified in menu entry of grub.However, the system
boots up properly on reboots.

----------------------------------------- >8 ---------------------------------------------

title SUSE Linux Enterprise Server 11 SP2

    root (hd0,1)

    kernel /boot/vmlinuz-<version>-default resume=/dev/sda1 splash=silent showopts

    initrd /boot/initrd-<version>-default

----------------------------------------- >8 ---------------------------------------------

Is this expected behavior for grub ? or it might be something specific for SLES11SP2 (falling on resume device)?

Can anyone please help understand this?

Thanks,

Chaitanya
