I was wondering what really needs to be done to switch to nptl on an existing 2.6 system.
According to this document: http://gentoo-wiki.com/NPTL#Switching_to_NPTL you don't need to recompile anything other than glibc to gain the full end-user performance benefits of nptl (though it does suggest doing a --newuse rebuild of world, the only changed ebuild is glibc itself). However, according to this document: http://www.gentoo.org/doc/en/migration-to-2.6.xml#doc_chap10 you must do a complete rebuild of all packages on the system (using the --emptytree emerge flag) in order to gain the benefits of nptl. Even more interesting, someone I was chatting with online suggested that only a few key programs besides glibc needed to be recompiled, to avoid problems. I was wondering, which is the accurate method of switching? If there are a few "problem" packages that should be rebuilt, which ones are they?
