I am starting to suspect the latter and am willing to upgrade
(though not my kernel, which has a few non-standard drivers that
I might not get running again :-).

What glibc should I have for 2.2.13? will the latest do or are there
inter-compatibility problems that mean I need a specific version?

(and where to get it... :-)

thanks
