Full ACK. IMHO it should be specified which environment variables are passed to the maintainer scripts from the outside, and any variable not on the list should be unset (or given their default values). Off the top of my head, I believe the only variables that would qualify to be passed through would be: - the locale variables (the user might want to see localized messages) such as LANG, LANGUAGE, LC_* - TERM, possibly DISPLAY (for debconf and similar prompts) Though if I understand debconf correctly the maintainer scripts don't actually need the DISPLAY variable, as they use a socket to communicate with debconf, or am I wrong there? - LD_PRELOAD (to support eatmydata), though that could be argued Maybe there are cases for others, but I don't think the list should be much longer than that.
