Ok hab jetzt was gefunden warum man nich glib 2.2 verwenden soll
Stand in der Faq der freestandards.org: "What's the danger in using glibc 2.2?
Applications linked against glibc 2.2 are less likely to run on systems based on glibc 2.1.
On the other hand, if application developers build their binaries using a glibc 2.1 system, they are much more likely to have executables that will work on both glibc 2.1 and 2.2 systems."
Das gilt also hauptsächlich für entwickler die nur binarys rausbringen. bzw.binarypakete für verschiedene distris von ihrem proggy schnüren.
