BIG disadvantage: if one physical disk (or even just physical partition) in an LVM fails your whole file system is gone. No repair possible. And another BIG disadvantage on dual systems with Windows: Unlike "traditional" ext3 partitions you may access read/write from Windows you will not be able to access anything on an LVM. Practical conclusion: except on systems keeping non-unique temporary data (example for such data: scans of existing documents for further processing and later archival) stay away from LVM. We should not forget we are paying Redhat a price for getting "free" Fedora: we are Guinea pigs for in most situations pretty useless staff like selinux and lvm. Thats why these are installation defaults. I do not know e.g. about a single company reducing its profits or increasing its losses by not having selinux. Military and similar people in their special way of thinking just love selinux and even LVM. LVM gives you the possibility to somehow use scattered parts (disks from otherwise broken PCs) and turn them into one single large disk for a running system (until the next bomb explodes). Therefore: anyone who likes to support all the military woldwide as potential Redhat customers should spent hours and hours testing selinux for Fedora. ;-) FMF
