[chef] question on bootstrapping a particular version of chef-server

[< >]

I am trying to find out if there is a way to bootstrap a particular version of
chef-server using chef-solo. Currently, the Opscode wiki talks about using
bootstrap-latest.tar.gz which gives me 0.10.8 and I would like to get 0.10.6. 
I
couldn’t find any documentation on selecting a particular version.
 
I have tried bootstrap-0.10.6.tar.gz & bootstrap-0.10.6-1.tar.gz but to no
avail. 
 
thanks in advance!
