I would like to say welcome to everyone who decide to test Fedora 14.

But I also want to tell something about a little problems with LVM.

As long as Fedora 13 and Fedora 14 uses LVM, its volume name looks like:
LV Name /dev/VolGroup01/LogVol00

No one and no where (or may be I was not very attentive) suggested to choose unique name, because VolGroup01 could be everything even BlaBla01.
Why I am saying all of this, because you probably will want to mount one from other, and if volume group name will be the same you wont be able to mount it and will have to rename it later.

So, if it is possible, when you will install on different disk choose something different from VolGroup01.

Please, correct me if I am wrong.

We always do it, e.g., LogVolRoot, LogVolVar and so on. It becomes more important with our iscsi servers, where we might have 8-15 different logical volumes, all the same size.
