I'm planning to install Fedora 9 on an external hard drive connected to a PC running XP (which is on the internal HD). Right now, the EHD uses fat32 and I'm unsure whether or not and how that should be changed. My understanding is that, for maximum flexibility, I should use an LVM, but I am completely inexperienced with this concept; how much guidance does the Fedora installation give for creating an LVM?
Fedora documentation says to use ext3 for non-LVM partitions, but I'm unsure as to what partitions I might want to use ext3 for because I don't see any reason not to make everything LVM (except for the boot partition). Do I have to use ext3, if not LVM? If not, what are the advantages/disadvantages to using fat32 or ntfs, and does it matter that my Windows OS uses ntfs?
I have plenty of space on my EHD; is it possible to keep the data that is currently on it intact for ANY file system(s) I choose to use for the Fedora installation?
When I start up my computer, I see the option to boot from a USB, so I'm assuming that I'll be able to boot from the EHD. Knowing this, will I need to do anything special before, during, or after the installation, in terms of booting, or should my installation experience be pretty much identical to the standard internal hard drive installation?
