I am installing Fedora Core 5 and I want to create logical volumes to where I can assign the file systems (so that I can extend or shrink them later, if necessary). The problem is that I can't find that option in the partition creation step of the installation process (I cannot use the Disk Druid due to memory limitations); I can only create LVMs. I looked at a lot of sites about logical volumes, but the commands lvcreate, vgcreate, pvcreate, etc. are only available once Linux is up and running (as far as I know), so I can't really use them at this stage.
How can I set up logical volumes during installation?
