If only that was the first answer, not the 3rd…
I don't think it can get more clearer than that?
How about, The function X will break because it expects LVM, or the script Y expects LVM. Something that will give me an idea if “I THINK” its worth the “risk”. I get this isn’t stack exchange, but its a support forum, generally that implies Question and Answer, not Question and Opinion.
What about our current system which is FreePBX Distro w/o LVM on CentOS 6. There is supposedly an upgrade script, will that transform the root partition into an LVM? I highly doubt it, so anybody who upgrades from FreePBX Distro 10, to FreePBX Distro 7 (SNG7) who doesn’t already use LVM, will have a “FreePBX System that will eventually break.”
I think you are lying, pushing LVM, not giving any examples to back up your claims, and generally just not being understanding that some users may not want LVM or may want to change aspects of the FreePBX Distro for their own reason…
