Hi Michael,

To preserve the permissions with tar the command to use is:

tar -cz --same-owner [-p | --same-permissions | --preserve-permissions] -f filename.tgz

this will create a tar file with same owner and file permissions. 
I don't understand the subtle differences between the -p 
--same-permissions or the --preserve-permissions, but only 
one is needed.  also when extracting the file I think that the
--same-owner and the --same-permissions must be set.  

Hope that this helps
