I know the use of localpurge isn't encourage. Would the use of path-exclude and path-include with dpkg[1] the same danger?

      Code:
cat /etc/dpkg/dpkg.cfg.d/excludes

# Drop locales except English
path-exclude=/usr/share/locale/*
path-include=/usr/share/locale/en/*
path-include=/usr/share/locale/en_US/*
path-include=/usr/share/locale/locale.alias

# Drop all translated manual pages
path-exclude=/usr/share/man/*
path-include=/usr/share/man/man[1-9]/*


All the locales and manuals use a third of a gigabyte
      Code:
du /usr/share/man /usr/share/locale/ -hs
37M   /usr/share/man
341M   /usr/share/locale/


While just the English locales is a quarter of a megabyte
      Code:
du /usr/share/locale/en /usr/share/locale/en_US/ -sh
252K   /usr/share/locale/en
20K   /usr/share/locale/en_US/

Given today's disk sizes, even in the light of smaller SSDs, I don't consider messing with locales is worth it (nor was it before).

However given the choice between two potentially lethal poisons, dpkg's path-{exclude,include} is definately a saner choice.

I am using it sometimes and never hit a problem so far, but as slh already said its usually not worth it.

My usecase for it are systems which operate from flashcards (becoming less of an issue now that I can afford even >=8GB microsd cards) or internal flash (does usually not grow – and my hardware is old and squeezing Debian into 256-512MB can be hard, so being able to drop stuff I don't need on those is great.

So if you have more than 10GB on your disk, stop thinking about it, the savings aren't big enough. If you have less (and especially far less) it might be an option, but even then there is usually a simpler/better way. Just think about what an MB costs you on average if you buy it in a store vs. how much time you have to invest to free some MBs this way.
