в чём собственно различия, плюсы и минусы для ядер 2.6.* ?
профиль desktop, x86
собираю glibc-2.5
localhost / # emerge -pv glibc
These are the packages that would be merged, in order:
Calculating dependencies... done!
[ebuild R ] sys-libs/glibc-2.5 USE="nls -build -glibc-compat20 -glibc-omitfp (-hardened) (-multilib) (-nptl) (-nptlonly) -profile (-selinux)" 0 kB
Total: 1 package (1 reinstall), Size of downloads: 0 kB
убраны оба флага а именно nptlonly и nptl, раньше все (не знаю почему) кричали "собирай с NPTL !",
то теперь когда флагов нет задаюсь вопросом: "а как отразится это на системе?"
