Whole System Encryption, LVM & Extended Partition

[Patrick Bartek <bartek047@yahoo.com>]

Did a couple of trial installs of Wheezy in VirtualBox in anticipation of the real thing on an as yet to be purchased notebook, and noticed something puzzling with the Guided-Encrypted-LVM partitioning option. (I've never done encryption on my systems before.)  The installer used a "classic" Extended partition, i.e. sda5, instead of a Primary one on which to place the LVMs: /, swap, /home.  /boot was a Primary, as expected.  Seems like a unneeded use of a logical partition layer on which to place another layer of logical partitions.

Any valid reason for doing this?

I'd prefer just two Primary partitions: /boot, and the balance of the drive for the encrypted LVM partitions. Any reasons for not doing it that way?

Thanks.
