I'm having a hard time understanding the thinking of the FC developers regarding the kernel "Optimize for size" option. Earlier 2.6.x kernels had this disabled, then they enabled it for a while, now it's disabled in current FC4 kernels. Meanwhile, the current RHEL4 kernel does enable the "Optimize for size" option, albeit with earlier compiler (GCC v3.4.4) and kernel (2.6.9. + patches) version. What's going on here? Does the value of this option change with differing kernel versions? How does one determine empirically whether this option should be enabled or not?
