Since I had a bad experience with LVM in F6, I've always ignored it

However, some people here do the default install of Fedora and it
uses LVM and in some cases people FORGET that they want their /home on
a separate partition. So the installer creates a single gigantic
logical volume in which everything is mounted.
See:
lvm> lvs -v

Before upgrading from Fedora 8 to 9, I want to separate the /home
partition from the rest of this. But I'm a little unsure of the best
approach because I anticipate trying the encrypted partition in Fedora
9. I would rather not just completely reformat the hard disk. I'd
like to set the /home stuff aside on its own place, and then let the
installer erase F8 and do a new install.
I should run lvm and shrink LogVol00 down with lvresize like this:
lvm> lvresize -L 100G
I should not run
lvm> lvcreate VolGroup00 -L 195.91G
I should wait for F9 to do that. Correct? I wait because encryption
cannot be put on retroactively a logical volume.
Suppose I do an upgrade to F9. That would not destroy LogVol00.
Suppose further I'm able to use the custom partition tool to have it
use my empty space for the /home.
The part that has me a bit confused is how I'll get the data off the
old /home directory in LogVol00 onto the encrypted /home that will
exist in LogVol02. I mean, if F9 creates a new /home in the empty
space, and it mounts that under /home (still thinking of it like an
ordinary partition, I guess), does that block access to /home on
LogVol00 ?
If this were me, I would hook up a USB external drive, back up to that,
do the install, copy the data back, and be happy.
And, because I'm moderately paranoid, I'd save it on the external drive
encrypted.
The most common thing to forget when reinstalling is saving the host
keys for ssh and anything else you use with keys or certificates.
