Hardy - AMD64 server and i386 thin clients

I believe the amd64 Ubuntu installation installs amd64 client build
environment by default. Make sure you update your ltspfs ltsp-server and
ltsp-standalone packages (use synaptic or apt-get). Then I would run this
# sudo ltsp-build-client --arch i386

This will take some time, but will install your i386 environment. 

FYI - Remember anytime you need to update the client environment, keys,
kernel, etc. you need to add the --arch i386 option after your command.

Yes there are some issues running an amd64 ltsp server I have noticed: 
1) Flash - gnash flash (64bit) does not run on clients for some reason, 
2) local device behavior is wierd (i get devices popping up on all desktops,
but I don't know if this is an amd64 or i386 error, may be an ltsp or
configuration error), 
3) LDM_DirectX has poor video performance- worse than when using the ssh
encryption, which does not make sense.. means something is broken). 
Problem #1, flash (and java), can be fixed by using a 32 bit version of
firefox or by running firefox as local app, which is more complicated and
less desirable for user experience as requires switching between desktop and
local apps). Problems 2 and 3 may not be amd64 ltsp server issues and may be
present on all builds. Other than that, it works fine.

I hope this helps :-)
