The worst case scenario is that you spend too much time worrying about it. Some devs including me switched profile without rebuilding anything outside the normal updates. (Because the guidelines were not written up yet.) Things just kept working fine. What can go wrong is that you get random build failures at some point later (likely with a linker message about failed relocations). These indicate that the linker was instructed to combine PIE and non-PIE code, which doesnt work. So one of the involved packages has not been rebuilt yet and needs to be rebuilt. This is mostly happening when static libraries are involved. -- Andreas K. Hüttel dilfri...@gentoo.org Gentoo Linux developer (council, toolchain, perl, libreoffice, comrel)
