I definitely like the idea of moving the debug symbols out to /usr/lib/debug I'm another person who sometimes has multiple kernels sitting in /boot (which is one reason I'd like the debug symbols elsewhere!). I may shuffle those around by hand, and I'm sure I won't remember to shuffle around information under /usr/lib/debug. I also do things like cp -rp kernel kernel-PreBigChange where I save away a copy of the kernel for possible fallback (at some unknown future date), but I wouldn't need two copies of the debug info. When we build a kernel, could we tag it with some unique-ID (by putting that ID in a plain-text file inside the kernel's directory), and then that unique-ID could be used for finding the correct debug info under /usr/lib/debug? This way we wouldn't need to move around any of the debug info under /usr/lib/debug. And we could tell which sets of debug info should be removed by comparing the existing sets of debug info with the kernel-unique-ID's which still exist under /boot. If debug tools need to have the debug-info for the booted kernel to be in a fixed location, then maybe the boot-up process could create a symlink from some fixed pathname to the correct debug info for the kernel which the system booted up on. -- Garance Alistair Drosehn = dro...@rpi.edu Senior Systems Programmer or g...@freebsd.org Rensselaer Polytechnic Institute; Troy, NY; USA _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
