LD_ASSUME_KERNEL is going to stay, it is a dynamic linker mechanism of selecting libraries based on their requirements. For details see http://people.redhat.com/drepper/assumekernel.html FC3 and RHEL4 are most probably going to support both threading systems like FC2/RHEL3, whether LinuxThreads will be nuked immediately after that or somewhat later is undecided yet. At least the exact kernel version numbers might change even for FC3/RHEL4 though, if e.g. NPTL libs require say 2.6.7+ kernels instead of 2.4.20+. Jakub
