134 Reduce the disk usage by deleting all man pages and doc files (harsh). APT will be configured to use compressed package repository lists and no package caching files. If `ENABLE_MINGPU`=true unnecessary start.elf and fixup.dat files will also be removed from the boot partition. This will make it possible to generate output OS images with about 160MB of used disk space. It's recommended to use this parameter in combination with `ENABLE_MINBASE`=true.
