[chef] chef server 11 packages for ubuntu

[Kirill Timofeev < >]

Folks,

I created the following script to automatically download latest chef 
server 11 ubuntu packages and add them to local repository:

#!/bin/bash
set -u -e
exec >> $0.log 2>&1

PLATFORM=ubuntu
PLATFORM_VERSION=12.04
ARCHITECTURE=x86_64
MAX_LOG_SIZE=1000000

PKG_URL="http://www.opscode.com/chef/download-server?p=${PLATFORM}&pv=${PLATFORM_VERSION}&m=${ARCHITECTURE}&v=latest&prerelease=true&nightlies=true";
LOCATION_FILE=$HOME/chef-server-location

old_location=$(cat $LOCATION_FILE)
new_location=$(curl -sIL "$PKG_URL"|grep ^Location)
[ "$old_location" == "$new_location" ] && exit
echo "$(date) started"
wget -nv --content-disposition "$PKG_URL"
mv chef-server_11*.deb /var/www/deb-box/incoming/precise/testing
echo "$new_location" >$LOCATION_FILE
echo "$(date) completed"
(($(stat -c %s $0.log) > $MAX_LOG_SIZE)) && mv $0.log $0.log.old

During last 3 days this script downloaded the following files:

chef-server_11.0.0-alpha.3+20130130075202.git.38.3332a80-1.ubuntu.11.04_amd64.deb
chef-server_11.0.0-alpha.3+20130128075214.git.37.d143b92-1.ubuntu.12.04_amd64.deb
chef-server_11.0.0-alpha.3+20130129075201.git.38.3332a80-1.ubuntu.11.04_amd64.deb
chef-server_11.0.0-alpha.3+20130129051708.git.38.3332a80-1.ubuntu.12.04_amd64.deb

Do I understand correctly that 11.04 in the name corresponds to ubuntu 
version this package is intended for? If yes looks like setting pv 
parameter doesn't work as expected. May I ask somebody aware of details 
clarify this?

Thanks,
Kirill.
