Before mirroring a complete Ubuntu / Debian repository on your hard drive, you want for sure have an estimation of the "weight" of all packages.
This script computes the total size of various Debian-based repositories by means of downloading the Packages.gz and making a sum of the size of every package. Of course, there are many shared packages between different versions of the same Linux distro. So this script will compute the max possible size.
Enjoy it!
I got the following results:..
Summary [Feb 9, 2012]
UBUNTU TOTAL SIZE = 466993 MB [456 GB] *
DEBIAN TOTAL SIZE = 184712 MB [180 GB] **
DEBIAN-SECURITY TOTAL SIZE = 22148 MB [21 GB] **
DEBIAN-VOLATILE TOTAL SIZE = 489 MB [0 GB] **
TOTAL SIZE: ~658 GB
* Considering lucid, maverick, natty, oneiric and precise, with i386 and amd64 architectures, and the components main, multiverse, restricted and universe
** Considering lenny and squeeze with i386, amd64, armel and arm architectures, and the components main, contrib and non-free

Various Java VM on my Debian / Ubuntu. What can I do?
The situation
Many of us prefer Sun JVM (Oracle now) for historical or non-historical reasons. Many of us also prefer Debian, Ubuntu and/or even Red Hat. But when we go and install LibreOffice (for example), via apt-get other powerful player arrives: openjdk. I don't want to discuss which JVM implementation is the most "appropriate" for us, you or them. There is a fact, many JVM can and should coexists pacifically.
But the question persists
- After installing various Java-dependant packages on my GNU/Linux OS preferred distribution, and I issue the javac command, which JVM compiler is invoked?
- How can I set my preferred Java implementation per command basis?
The solution
The Debian alternatives system is devoted to solve the problem of choosing the default preferred implementation of various kinds of programs: text editors, mail agents, JVM, etc.
The options are settled via update-alternatives in a terminal and there is also a graphical version called galternatives.
The Example
This script sets various' Sun JVM (Oracle now) commands as the default alternatives for: java packaging, java VM, java compiler, javadoc, etc. It runs update-alternatives command several times, one per java command.
