Bug#929706: sgml-base: preinst may fail *silently*

[Ralf Treinen <treinen@debian.org>]

Hello,

the preinst of sgml-base contains

  if [ ! -d /var/lib/sgml-base ]
  then
    mkdir /var/lib/sgml-base 2>/dev/null
  fi

and then the same for /etc/sgml. The problem is that this fails
when /var/lib/sgml-base or /etc/sgml is a regular file, and will do
that without any error message.

I suggest to replace the whole preinst script by

if [ "$1" = "install" -o "$1" = "upgrade" ]
then
  mkdir -p /var/lib/sgml-base /etc/sgml
fi

-Ralf.
