[Bug 1048123] Re: Installer try to exec scripts under /tmp

This is not a supported configuration in Ubuntu.  You might want to find
a better security guide.

The exec is being done as part of pre-configuration of debconf.  You can
change this behavior by editing /etc/apt/apt.conf.d/70debconf, but it's
not advisable.

** Changed in: resolvconf (Ubuntu)

Title:
  Installer try to exec scripts under  /tmp

Status in “resolvconf” package in Ubuntu:
  Invalid

Bug description:
  Ubuntu 12.04, i386 on thinkpad x41

  Got the new resolvconf package by update today, but the update did not
  install cleanly.

  Vorkonfiguration der Pakete ...
  Can't exec "/tmp/resolvconf.config.31971": Keine Berechtigung at /usr/share/perl/5.14/IPC/Open3.pm line 186.
  open2: exec of /tmp/resolvconf.config.31971 configure 1.63ubuntu15 failed at /usr/share/perl5/Debconf/ConfModule.pm line 59

  The /tmp is mounted as nonexec like described in linux security
  guides, so the way to exec programs there is a bit ugly.

  /etc/fstab
  tmpfs /var/tmp tmpfs noexec,defaults,noatime 0 0
