Using upgraded machine nearby to upgrade a machine?
Apologies if this is a wrong forum for this topic or this has been asked before (tried searching for it).
I recently upgraded Ubuntu on my 64-bit desktop, from jaunty to karmic. Smoothest upgrade experience I have ever had (even better than L to SL in case of Mac). Kudos.
My question was regarding saving the bandwidth (and time) to upgrade another machine I have. For instance, I have machines A and B which are at version x. A got upgraded to x.next and it of course downloaded all the packages it needed (it took about 10 hours). Can B (which is more-or-less identical in terms of contents) leverage this fact to upgrade itself to x.next without having to download all of the same packages from remote repositories?
Thanks and Regards,
