Thank you for the letter, Lamont!

Procedure you described requires a so much time to complete.

Tomorrow I end up the following pipeline:

1. Create only one 4Gb plain root partition (no LVM) which holds a
entire system and my application. It's used in a development and test
environment. The actual stored data is about a 1.5 Gb. I am pretty
sure the base system it never fills entire 4 Gb in my case.

2. To build a production server I am bytecopy the root partition to a
new box (only a few minutes), boot from it, create LVM in a free space
and moves application from root to LVM.
Production database now have space to grow. Also I get rid of equal
UUID problem.

Additionally there is no need for kickstart process is VM environment
- I just need to setup OS one time, and then when I need another box I
just clone initial setup - it takes a few second. For testing and
development VM overhead is ok.
