installing ubuntu from bootable usb, using lvm

[bruce]

Hi.

New laptop for testing/installing Ubuntu is on the way. In preparation
for installing, I've been researching the usb/bootable flash drive
process. In particular, trying to wrap my head around the
partition/LVM/fstab process.

So far, haven't found any tutorial with screen shots showing the
Install process invoking the LVM process (volGroup, LogicalVol, etc)

Does anyone have any pointers/sites to illustrate this process?

I've seen a few sites that illustrate the partition setup:
example partition

/dev/sda --- internal 128G ssd
 /dev/sda1  ext4  /boot     1G
 /dev/sda2  ext4  /root     1G
 /dev/sda3  swap           10G
 /dev/sda4  ext4  /       110G

/dev/sdb --- exetrnal 1TB hdd
 /dev/sdb1  ext4  /etc     1G
 /dev/sdb2  ext4           10G
 /dev/sdb3  ext4  /       110G

But then the examples, drop into "go ahead and then install"

Does the install GUI process even allow the LVM attributes to be setup
for  the initial drives (I got the feeling it does), or do you have to
install, and then go back, and reimplement LVM?

So, I'm assuming I'm missing some pieces of the puzzle.

thanks
