[Debconf-devel] Bug#782463: debconf: purging package that uses debconf fails if postrm writes to stdout

[Tristan Schmelcher]

Doh. With word wrap:

Packages that use debconf automatically get a postrm fragment for
purge that sources confmodule. This breaks if the maintainer has a
custom postrm that can write to stdout before the #DEBHELPER# line,

#DEBHELPER# line is reached for the second time. This results in an
unpurgeable package. Here is a minimal package that repros the
problem:

through a helper script to do the redirection before running any
maintainer code, such as with this patch:
