Hi Roberto,

There are two things to the removal of the docs:

1. no package should assume that some folders that are not provided by a direct dependency exists (=> packaging bug of openjdk-11-jre-headless)
2. I'm really wondering if simply clearing these folders is the right approach.
Instead, you could instruct dpkg via dpkg.conf to not install files into particular paths:

Simply add a drop-in to: /etc/dpkg/dpkg.cfg.d/ with dpkg options for path exclusions:

# Delete man pages
path-exclude=/usr/share/man/*

# Delete docs
path-exclude=/usr/share/doc/*
path-include=/usr/share/doc/*/copyright

Of course, this has to be done prior to any package installation and at best not from a package itself.
This would also solve the issue that docs are installed when installing packages into the live image (outside of ISAR).
