Another LVM question

["Jerry Feldman-2" <user=4@nabble.blu.org>]

 We've had a recent discussion on partitions and file systems and a 
couple of LVM questions.  I currently have a new computer that came 
configured with Centos5 preinstalled with partitions layed out (160GB 
SATA): 
/bin/sda1 ext3 /boot 
/bin/sda2 ext3 / 
/bin/sda3 swap 
/bin/sda4 Extended 
/bin/sda5 ext 3 /home 

What I was thinking of doing was to blow away /bin/sda3,4 and 5, and 
create a volume group with a couple of logical volumes. An alternative 
would be to backup the root file system, and simply create /dev/sda2 as 
LVM.  I also will have a 120GB USB drive from my old computer to use 
to backup /home once I remove it from my old system.  I don't recall 
the specific sizes of the partitions off hand. But, I think my logical 
choices are: 
1. Just leave everything as it is. 
2. Leave root in sda2 and set everything else as LVM ** This is my 
preferred choice 
3. Leave root and swap alone, set up sda4 as LVM. 
4. Move everything to LVM.  Here there are 2 methods. 
The first is stepwise - do option 2, then create root in a logical 
volume, update Grub, then once that is done, I can manually shrink 
sda2. The second is backing up root to a USB drive, run a CENTOS 
rescue, create the LVM, then restore root into the appropriate logical 
volume. 

I certainly have a few more choices. With option 2, I could move /var 
and /tmp into a logical volume and physically shrink root down, but I 
would still need to leave room for updates and new software.
