Going from glibc 2.1.94 to 2.2.4 should be OK, as 2.1.94 was very very

The way it *should* work is that apps running depending on 2.1.94 will still
be running (all using their shared copy of glibc), but once they exit and
restart (or you reboot), they'll pick up the new glibc library. That's the
idea at least.
Good backups are always a good idea though! :-)
