[Debconf-devel] Bug#439763: debconf: hangs on puppet installs on preseed install

[Jacob Luna Lundberg]

This is still happening with squeeze.  It's something in the environment 
left over from the installer.  This bit of bash is working for me in my 
post-install script:


# Environment
unset -v $(set | sed -e 's/=.*//g' | egrep -v '^(BASH*|HO*|IFS|PATH*|PWD|SHELL*|TERM*)')
. /etc/profile
export LANG=en_US.UTF-8


Before that, the shell variables are:
-------------------------------------

BASH=/bin/bash
BASHOPTS=cmdhist:extquote:force_fignore:hostcomplete:interactive_comments:progcomp:promptvars:sourcepath
BASH_ALIASES=()
