I just happened to run into the same or similar issues recently when
attempting to fully automate differing un-attended system builds with
ubuntu 14.04 on amd64
I was able to make the provided -atomic and -home recipes work, but they don't
offer any control over the sizing of the logical volumes.
The -multi recipe doesn't work.
The expert-recipes don't work either, no matter what I specified, the
end was result was the same, I'd get a /root a /swap_1 logical volume
and /boot partition, and never close to the sizes specified, nor the
filesystem type specified, nor the logical volume name specified :-)
Below are the options and recipe used.
I was about to try using kickstart versus preseed to try and setup LVM on
ubuntu how I want. On my rhel/centos systems customizing LVM is a breeze with
kickstart automation

# You can choose one of the three predefined partitioning recipes:

# Give the default VG a name
