I would like to recompile / recompile all Debian packages with certain flags.
How can I do this with a smaller team as possible?
I found that https://debian-administration.org/article/20/Rebuilding_Debian_packages , but he does not explain how to do this for all packages installed on the system.
Try this approach:
dpkg --get-selections > selections sudo dpkg --clear-selections sudo dpkg --set-selections < selections sudo apt-get --reinstall dselect-upgrade
