Disk space is so damn cheap today.... -Maxim -------- Original Message -------- Subject: What do people think about not installing a stripped /kernel ? Date: Mon, 18 Oct 2004 15:12:00 -0700 (PDT) From: Matthew Dillon Newsgroups: dragonfly.kernel The only cost is disk space... e.g. 3MB stripped kernel verses 16MB debug kernel. But the debug info isn't actually loaded into memory so the kernel load time and memory overhead is the same as with the stripped version. The issue is bug reports and kernel core dumps. I can't count the number of times I have had to carefully instruct people to retrieve their kernel.debug's for bug reporting purposes. And even my own debugging would be more convenient if I didn't have to save off a separate copy of the debug version of the kernel. What I'm thinking of doing is having the installkernel target install the debug version rather then the stripped version unless told to install the stripped version with a new option, e.g. 'options INSTALL_STRIPPED'. We would ship full debug GENERIC kernels instead of stripped kernels. i.e. we aren't getting rid of the ability to install a stripped kernel, we just aren't making it the default any more. What do people think? -Matt
