Lintian tag information: command-with-path-in-maintainer-script (type: warning)

Description (from lintian-explain-tags)

The indicated program run in a maintainer script has a prepended path.
Programs called from maintainer scripts normally should not have a path
prepended. dpkg ensures that the PATH is set to a reasonable value, and
prepending a path may prevent the local administrator from using a
replacement version of a command for some local reason.

If the path is used to test a program for existence, please use if which
$program > /dev/null; then ….

If you intend to override this tag, please make sure that you are in
control of the installation path of the according program and that you
won't forget to change this maintainer script, too, if you ever move that
program around.

Please refer to Introduction to package maintainer scripts (Section 6.1)
in the Debian Policy Manual, Best practices around security (Section 6.4)
in the Debian Developer's Reference, Bug#769845, Bug#807695, and
https://lists.debian.org/debian-devel/2014/11/msg00044.html for details.
