I agree with Andreas.

There are a few issues to consider for ISVs. First off, as Ted mentioned 
the adoption of newer distributions by customers. Even if customers 
install SLES 11 and/or RHEL 6 soon after they are released there will 
not be a wholesale change. Meaning SLES 10 and RHEL 5 support will be 
important for ISVs for a long time. We are just getting over the RHEL 3 
problem, thus we should do our best not to create a SLES 10/RHEL 5 
problem. This would dictate that LSB 4.0 specifies glibc 2.4. Secondly, 
it will take ISVs probably the better part of a year to get certified 
after the LSB contains the interfaces a given application needs. If this 
process can be started sooner, i.e. on existing distributions than ISVs 
can get a head start on the certification process.
