The main thing is that glibc is built against linux-headers, rather than the source in /usr/src/linux. A few other things depend on them as well. So, after upgrading linux-headers you should rebuild glibc. Upgraded headers replace the old ones, so you don't need to do any extra tricks. 2.4 headers work just fine with 2.6 kernels. Right now the only reason to upgrade to linux-headers-2.6.0 is to get nptl support, which, in my experience, does give a considerable performance boost. Especially if you're running a SMP system. The problem of course is that there are some programs which fail to compile with the new headers (namely xfree (obviously) and svgalib, for which there is no patch at this point) and thus make it a bit more challenging to run the system. -- Jani-Matti H�tinen -- [EMAIL PROTECTED] mailing list
