LVM and encrypted partitions

[Andrew Henry <adhenry@bredband.net>]

I recently installed the latest Debian stable on a server and chose
encrypted LVM using the guided partitioning option.  I chose seperate
partitions for /home, /var, /tmp, / and /usr.

All works fine, but I have one query:

the first partition was for /boot and is unencrypted.  The second
partition was ???  What was it?  Was it LVM containing a bunch of
dm-crypt partitions or was it one dm-crypt partition containing a bunch
of LVM partitions?

If I assume that it is an encrypted partition containing a bunch of LVM
partitions, does this mean I can still use LVM tools to resize my
partitions?  What tools are there for managing LVM within an encrypted
partition?

Regards,
andrew
