Comment(by splotz90):

 The search command does something for LFS ...

 This command set the root-device for GRUB to hd0,1:
 set root=(hd0,1)

 After that GRUB will look for a partiton with the UUID ''06910bbb-95ff-

 search --no-floppy --fs-uuid --set 06910bbb-95ff-43f7-ac74-d44fe9caecf1

 If there's no partition with this UUID, GRUB will use the device set
 before (hd0,1). If a partition with this UUID exists, GRUB will boot from
 this partiton. In the most cases the partition set with the first command
 will have the UUID in the search command.

 This means: GRUB can boot if the device has changed (for example hd0,1 -->
 hd1,1) and if a new filesystem was created.
