Package: cacti-spine
Version: 1.1.37-1~bpo9+1
Severity: normal

Dear Maintainer,

   * What led up to the situation?
        Upgrading from cacti-spine_1.1.37-1~bpo9+1 to cacti-spine_1.1.37-2~bpo9+1 caused execution of cacti-spine for non-root users to break, even with setuid bits set for either just user or all.
   * What exactly did you do (or not do) that was effective (or
        Attempted to set setuid bits on /usr/sbin/spine to permit execution by non-root users (eg, cacti). Attempted to debug by running "/usr/sbnin/spine -H=180 -R -S -V=5" and "/usr/sbin/spine -h" as both root and cacti users.
   * What was the outcome of this action?
        /usr/sbin/spine would fail silently when executed by cacti user but would run successfully when executed by root user. Example: 
    cacti at mon1:~# /usr/sbin/spine -H=180 -R -S -V=5
    cacti at mon1:~#
    cacti at mon1:~# /usr/sbin/spine -h
    cacti at mon1:~#

   * What outcome did you expect instead?
        Expected spine to execute successfully for non-root cacti user once setuid bit(s) were set.

Re-installing cacti-spine_1.1.37-2~bpo9+1 had no effect, Removing and re-adding setuid bits had no effect. Once I rolled the package back to cacti-spine_1.1.37-1~bpo9+1 and set the setuid bit for the user it started executing successfully again for the no-root cacti user with no other changes necessary.
