Hello Tony,
 
I am not readily available the coming weeks, so I am afraid that I cannot help a lot at the moment, but I do have a question:
 
Why bother with ia32 libraries?
 
If you go to the ubuntu download webpage, you can also select to download a 64bits Ubuntu version: http://www.ubuntu.com/GetUbuntu/download
 
I wonder: how many packages will be missing if we install a 64 bits version? Source code is readily available, so we can try what compiles properly under 64 bits. Packages that cause problems need to be either fixed or executed in a 32bits environment (e.g. ia32).
 
Ain't this approach better? I must honestly state that I don't exactly know how much work will be involved in this, but it must be given a try somewhere sometime anyway? Right?

Hello, Martijn.

Olivier Riche is taking over some of Ulrich's responsibilities, so that
problem will soon be resolved. However, my question was do you think we
should do something immediately about moving our upgraded NBX's to run a
64-bit kernel with a 32-bit Bio-Linux 5.0 userland?

My reluctance to move to a 64-bit Ubuntu is because I want to make use
of Bio-Linux 5.0, which is only available to us as 32-bit binary deb's.
My attitude to running 64-bit Ubuntu has changed since I tried out the
"ia32" libraries and I want to discuss the possibility of using 64-bit.

The NBX hardware upgrade we're doing makes it very easy to clone an NBX,
so I could send you a 512GB hard disk with the 64-bit kernel and 32-bit
Bio-Linux 5.0 in /usr/local for you to try out on "nbx5". Please let me
know what you think?

Bye,

   Tony
