Hi All,
I have serveral servers with Intel's Xeon EM64T CPU's, most of them are running lunar (1.5.x) without any problems. We recently bought another 2 and would like them to be as optimized as possible and thus tried various x86_64 distro's since lunar doesn't have that flavour.
After 3 weeks of fiddling (extensive testing) with a.o. FC4 and Gentoo 1.6.14 we decided that none of them neither installs nor works as smoothly as Lunar does 
The only thing left for us to do now is try Lunar. We did try 1.6.0RC3, but couldn't get the software-RAID to work properly, so it seems that we bound to a 2.4 kernel as well.
My questions now:
Is a x86_64 version of Lunar being worked on?
Suppose we install these machines with a 2.4-based Lunar, how hard is it going to be to "upgrade" them once a 64-bit version is available without completely reinstalling the machines?
Does anyone have some usefull input?
TIA

Very - the x86_64 installation will be purely 64bit - i.e. no 32bit compatibility layer (which means 2 glibc's, two binutils' etc). On top of that it will be 2.6-kernel based first - it's unlikely a 2.4-kernel based version for x86_64 will come out soon - if any.
The biggest problem with porting lunar is availability of equipment combined with time and experience - I have the machines at work but not the free time (they're firewalled too so I could not work remotely anyway). On top of that nobody donates me a box for at home :^(
Su.se is currently setting up a lunar-based cluster and we have one developer working on getting x86_64 to work on that - my hopes are set on that for now.
