This long post (in a long thread) sums up a couple of problems in
support and stuff for amd64. I'm being asked NOW for advice and help 
by a couple of colleagues who are planning for a potential AMD64 cluster.  
They haven't bought the hardware yet but are being very sensible and 
specifying the libraries and applications they want from the cluster 
vendor (mostly math / physics libraries): they are not explicitly
specifying a distribution.  They keep asking me - "Is <foo> library / binary 
available in Linux" and seem surprised when I say "Not in Red Hat Enterprise 
Linux (or SuSE as far as I know) but it is in Debian"  I run a tiny cluster 
for testing on 32 bit: they know I'm a Debian zealot but they thought 
all Linux was the same. It isn't :)

I need to convince enterprise bean counters that 64 bit Linux is a valid
idea. They'll probably want to buy Red Hat in any event- but probably don't 
know the extent of the support they'll get outside the base operating system. 
[I can't imagine RH supporting GMP library problems with enthusiasm, for
example].  Pure64 seems to me to be an ideal solution in the short ->
medium term: being 64 bit only will probably save the mathematicians the
trouble of one more variable quantity :)

Can we _please_ stop the arguments: some (few) people need 64 bit Debian 
_now_ on AMD64. Please put amd64 pure64 into sid ASAP: flag it as the interim
solution till sarge+1 / sarge+2 and multiarch. That way, it stands a
chance of reaching testing by Sept/October ready for sarge point release
whenever :)

Just my 0.02 <insert monetary units here> Running Debian on 0.0001 of
a decent sized cluster here :)
