I'm under the impression that RedHat implemented the

NPTL-enabled kernel and libs with RedHat 9.
On the other hand, some development shops I'm working with are
(naively?) assuming that LD_ASSUME_KERNEL is a permanent feature that
will allow them to run "properly".
- How long will two threading systems be supported via LD_ASSUME_KERNEL?
- Will FC3 (and RHEL4?) also support regression via LD_ASSUME_KERNEL?
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+.
