Hi, I've got a question for the prelink, the dpkg maintainer, or both. That's why I send this mail to you together.
Recently I turned on prelinking on my Debian unstable box. Now I've noticed that start-stop-daemon cannot stop running daemons anymore. This interferes with upgrading packages as an attempt is made to run two instances of a daemon at the same time resulting in failure and sometimes cryptic error messages. As an example, on my system "/etc/init.d/portmap stop" which does a "start-stop-daemon --stop --quiet --oknodo --exec /sbin/portmap" does not work and the portmapper daemon keeps on running. I believe this is because of the way start-stop-daemon checks for instances of the /sbin/portmap executable. An "ls -l" of /proc/127 (127 being the pid of the portmapper daemon) gives: # ls -l /proc/127 total 0 -r--r--r-- 1 root root 0 Nov 14 06:44 cmdline lrwxrwxrwx 1 root root 0 Nov 14 06:44 cwd -> // -r-------- 1 root root 0 Nov 14 06:44 environ lrwxrwxrwx 1 root root 0 Nov 14 06:44 exe -> /sbin/portmap.#prelink#.II5pc2 (deleted) dr-x------ 2 root root 0 Nov 14 06:44 fd/ -r--r--r-- 1 root root 0 Nov 14 06:44 maps -rw------- 1 root root 0 Nov 14 06:44 mem -r--r--r-- 1 root root 0 Nov 14 06:44 mounts lrwxrwxrwx 1 root root 0 Nov 14 06:44 root -> // -r--r--r-- 1 root root 0 Nov 14 06:44 stat -r--r--r-- 1 root root 0 Nov 14 06:44 statm -r--r--r-- 1 root root 0 Nov 14 06:44 status Notice the target of the exe symlink. Is this different target the reason why start-stop-daemon cannot stop the running portmapper daemon anymore? If so, what must be changed? I can think of some options: - Binaries like the portmapper daemon shouldn't be prelinked at all - The prelinking program is responsible for creating this kind of target name and should be changed - The start-stop-daemon program should be changed to cope with this kind of target name - The kernel is at fault for creating these target names and should be patched What is your opinion in this matter and what actions do you think I should take? Thanks in advance, Arjan
