I have some 32-bit kit I would like to continue to use, with either SL4
or better SL5. It's relatively old kit but still we would be throwing
away about 15% of our CPU capacity and some useful redundancy for tests
if we can't use it.
Are there VOs that will not want to use gLite 3.1 sites when 3.2 comes out?
