Seriously, a quick google search on the matter spits _many_ results. One of those is this cute one-liner: http://jcmdev0.blogspot.com/2009/12/one-liner-to-extract-vmlinuz-to-vmlinux.html which unfortunately is wrong (byte pattern is screwed up), but with a quick fix it becomes: dd if=/boot/vmlinuz skip=`grep -a -b -o -m 1 -e $'\x1f\x8b\x08\x00' /boot/vmlinuz | cut -d: -f 1` bs=1 | zcat > /tmp/vmlinux which should work alright. -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to [email protected] Please read the FAQ at http://kernelnewbies.org/FAQ
