Hi, I am building a package which should be able to interact either with PostgreSQL (using php4-pgsql and postgresql-client) or MySQL (using php4-mysql and mysql-client). My first idea was this line:
Depends: (php4-pgsql, postgresql-client) | (php4-mysql, mysql-client) Of course, life was not too gentle on me, as this is not legal. I did not want to resort to the simpler: Depends: php4-pgsql | php4-mysql, postgresql-client | mysql-client because it could lead to (very unlikely but still existent) problems - What if the user has php4-pgsql and mysql-client? A friend of mine came up with a brilliant idea: Depends: php4, php4-pgsql | php4-mysql, php4-pgsql | mysql-client, postgresql-client | php4-mysql, postgresql-client | mysql-client Yes, it is harder for the human eye to parse, but it builds the correct truth values, and apt-get can understand it. Life was good until a couple of minutes ago, when I ran Lintian on my package, only to find out: E: tutos: package-has-a-duplicate-relation php4-pgsql | php4-mysql, php4-pgsql | mysql-client N: N: The package seems to declare a relation on another package which is N: already implied by other relations it declares, and is therefore N: redundant. This is not only sloppy but can break some tools N: E: tutos: package-has-a-duplicate-relation php4-pgsql | php4-mysql, postgresql-client | php4-mysql E: tutos: package-has-a-duplicate-relation php4-pgsql | mysql-client, postgresql-client | mysql-client E: tutos: package-has-a-duplicate-relation postgresql-client | php4-mysql, postgresql-client | mysql-client Which means, no matter how elegant it is, it is still not good :-( Does anyone have an idea on how to make this work correctly?
