What's the file system type in FC4

[Parameshwara Bhat]

Dear List,

FC4 seems to use Logical Volumes by default. I installed FC4 as new 
installation as it failed to upgrade from FC4-Test.(3.91).

Now sometimes I work in other distributions of Linux and want to be able to 
mount the partition where FC4 is installed. Setting filesystem type as FC3 
doesn't work to mount. What do I specify for filesystem type of FC4 which in 
FC4 is LVG 0 volume 1

Thanks,
