With replacing

kernel /vmlinuz-2.6.22.9-91.fc7 ro root=/dev/sdc2 rhgb

with

kernel /vmlinuz-2.6.22.9-91.fc7 ro root=/dev/sda1 rhgb

I could boot in /dev/sda1 where there is a copy of /dev/sdc3.

I would prefer to use /dev/sda for F7 instead of using /dev/sdc, as
/dev/sda is much larger. If I make a copy of the partition /dev/sdc2
in a partition inside /dev/sda, should I expect F7 working fine fully
on /dev/sda? If so, where should I configure that the two partitions
in /dev/sda are two logical volumes?
