---------------------
If you're using tools that use chroots, please be aware that
libpam-tmpdir only creates the directory and sets TMPDIR whenever a
new PAM session is started. This means that some tools which do not
reset TMPDIR, nor start a new PAM session might end up with TMPDIR
pointing to a non-existent directory. An example of such as tool
(when this is written) is pbuilder.
To work around this, either enable a hook that unsets TMPDIR or one
that creates TMPDIR if it is not present already.
