guided lvm encrypted partitioning in Debian 8.1

[Patryk Hanckowiak <pathanck@gmail.com>]

Hi.
I seem to have found a bug in the guided (LVM encrypted) partitioning
schema for Debian 8.1.

The installation created separate partitions for /var, /tmp and /home
but did not create a separate /usr. I ended up with a partitioning
schema with an 8 GB root (/) partition, which is too small for desktop -
/usr is in /. This seems to be a bug, as an old partitioning guide seems
to have been correct, and did install a separate /usr partition:
https://debian-handbook.info/browse/stable/sect.installation-steps.html

The installer gave only three options:
1) Everything on one partition;
2) separate /home;
3) separate /var, /tmp, /home;

This is a bug.

If possible, please let me know if this was fixed and if the bug was
confirmed.

Regards,
