Bug#1017446: debian-policy: stress that preinst script that install by using base64 decode on self an elf binary is not a good stuff

[Bastien Roucariès <rouca@debian.org>]

Package: debian-policy
Version: 4.6.1.0
Severity: important

Dear Maintainer,

I will like to stress that this kind of stuff is bad:
https://salsa.debian.org/debian/isa-support/-/blob/master/debian/altivec-
support.preinst.in#L10

base64 encoded binary in maint script and mktemp on /usr/lib

I have no idea about documentating why it is bad. But for the sake of history
we must learn of mistake, and document it

Bastien
