[opensuse-packaging] Dependencies between packages and their YaST module (was: Re: [opensuse-factory] Yast improvment ide?)

ps: Why is the httpd module not pulled in when I install apache?
Because the apache package does not have Recommends: yast2-http-server in its specfile. The other way round is also possible: add Supplements: apache2 to the yast2-http-server package. (Open a bugreport and it might be added ;-) This would be useful for every YaST module, so maybe it {c,sh}ould be made a general policy: - "If there is a YaST module for a package, the package should recommend it" - or - - "each YaST module should have a Suplements: for the package it configures" This might even be the better solution because it is easier to check ("each YaST package must have at least one Supplements: statement") I'm cross-posting this mail to the opensuse-packaging mailinglist because packaging policies are better fitted there. Please answer only to the -packaging mailinglist if possible. (Packagers, do you like the above proposal?)

that might be difficult for things like yast2-mail or any other yast2 module that configures multiple alternative implementations. The reverse, as you noticed, however is not automatically verifyable with e.g. rpmlint. at least I don't know how..

Requires: smtp_daemon should work. Whatever package provides the smtp_daemon symbol will fit this.
or any other yast2 module that configures multiple alternative implementations.
Those packages should provide a common symbol which can be used in the Supplements: of the YaST package.

rpm -q --supplements yast2-foo (and check if it is != "(none)") should help - but I'm not a rpmlint expert ;-) The basic question is: which way is better? a) Package yast2-foo Supplemens: foo b) Package foo Recommends: yast2-foo Technically (from the dependency solving POV) both ways will work. The advantage of a) is that it can be checked automatically (as in "every YaST module is used to configure a package/functionality"). Another advantage is that the information which yast-foo package is used for package foo is kept at the right place which is the yast-foo package IMHO. Auto-checking b) would be very nice ("every package has a YaST module to configure it") - but I'm afraid this more a dream than doable in reality ;-) BTW: Even if rpmlint can not check this for now for whatever reason, it should at least be added to the packaging guidelines.

Out of interest, is it possible to Requires: smtp_daemon and Recommends: postfix; and what happens if you do that? -- Benjamin Weber --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-packaging+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-packaging+help@opensuse.org

As far as I know that does not work yet, as Recommends are processed in a seperate solver run (first only requires, then recommends). so the decision to go with the "wrong" smtp daemon was already taken.

That's not true, if the solver has multiple packages to choose from, it'll prefer recommended ones.
