sudo not properly cleaning out timestamp directory

[Marc Deslauriers]

Sudo 1.8.10 switched to a new time stamp file format that uses the monotonic clock. Timestamp files moved from /var/lib/sudo to /var/lib/sudo/ts.

At boot, the contents of the /var/lib/sudo/ts directory needs to be deleted, as per the warning in the build log:

configure: Warning: the /var/lib/sudo/ts directory must be cleared at boot time.
configure: You may need to create a startup item to do this.

The sudo package ships with both an init script and a systemd unit file. Unfortunately, the init script sets the date on the timestamp files to epoch, which is no longer the proper way to invalidate them. The systemd unit file doesn't seem to work at all.

This bug was fixed in the package sudo - 1.8.12-1ubuntu2

---------------
sudo (1.8.12-1ubuntu2) wily; urgency=medium

  * Use tmpfs location to store timestamp files (LP: #1458031)
    - debian/rules: change --with-rundir to /var/run/sudo
    - debian/rules, debian/sudo.service, debian/sudo.sudo.init: stop
      shipping init script and service file, as they are no longer
      necessary.
    - debian/*.preinst, debian/*.postinst, debian/*.postrm: remove old init
      script with dpkg-maintscript-helper.
    - debian/*.postinst: remove old /var/run/sudo to /var/lib/sudo
      transition code, remove old /var/lib/sudo/ts timestamp directory.
