Hello, I stumbled upon the following sentence in pacman.conf.5: repo-add /home/pkgs/custom.db.tar.gz /home/pkgs/*.pkg.tar.gz The above command will generate a compressed database named /home/pkgs/custom.db.tar.gz. Note that the database must be of the form defined in the configuration file and {ext} is a valid compression type as documented in repo-add(8). Although the example database name has the static extension ».gz« (which is currently used in Archlinux' Pacman), the following explanation mentions {ext} as a variable for the file extension. If this targets to use cases of Pacman in other distributions which possibly use a different extension, then the man page should explain this more detailed. Best Regards, Mario
