[CentOS] Making a clone of an LVM-based EL5 install

Hi Ben,

Off-list as Antonio had the same message, but I would HIGHLY recommend 
CloneZilla; it would only back up the used portion of the drive unlike 
dd (which would save you a lot of time), and it hasn't failed me yet in 
5 years. I recommend the "alternative-stable" release; it has more drivers.


(this is unrelated to the issue you fixed; clonezilla's image would also 
be missing the sata_nv driver)
