Excessive dependency list on system-config-printer
Last modified: 2007-11-30 17:10:49 EST
Description of problem: I have tried to setup a simple print server. Installed minimal configuration. After that, I attempted to install system-config-printer and got an excessively long dependency list. [install: system-config-printer 0.6.98-1.i386] I will install/upgrade these to satisfy the dependencies: [deps: perl-libxml-enno 1.02-30.noarch] [deps: Omni-foomatic 0.9.1-6.i386] [deps: ghostscript 7.07-25.i386] [deps: perl-libwww-perl 5.79-1.noarch] [deps: ttmkfdir 3.0.9-11.i386] [deps: xorg-x11-xfs 6.7.0-5.i386] [deps: m4 1.4.1-15.i386] [deps: mpage 2.5.3-7.i386] [deps: urw-fonts 2.1-7.noarch] [deps: libxslt 1.1.5-1.i386] [deps: pnm2ppa 1:1.04-10.i386] [deps: perl-DateManip 5.42a-1.noarch] [deps: chkfontpath 1.10.0-1.i386] [deps: alchemist 1.0.33-1.i386] [deps: PyXML 0.8.3-4.1.i386] [deps: perl-libxml-perl 0.07-29.noarch] [deps: VFlib2 2.25.6-21.i386] [deps: perl-Parse-Yapp 1.05-31.noarch] [deps: perl-XML-Dumper 0.71-1.noarch] [deps: perl-URI 1.30-1.noarch] [deps: foomatic 3.0.1-3.1.i386] [deps: xorg-x11-font-utils 6.7.0-5.i386] [deps: perl-XML-Encoding 1.01-25.noarch] [deps: Omni 0.9.1-6.i386] [deps: perl-XML-Parser 2.34-2.i386] [deps: ghostscript-fonts 5.50-11.noarch] Expected results: Do I really need VFlib2 to be able to configure printers? both PyXML and perl-XML-parser? x font server? libxslt?
If you think there is a specific requirement that is not ever needed, let me know. As for the ones you list: VFlib2: required by ghostscript, or else it won't start PyXML: used in system-config-printer directly perl-XML-parser: used by foomatic xfs: required by chkfontpath, which urw-fonts uses in its %pre/post. libxslt: required by alchemist
I am aware that it is not system-config-printer that directly requires all these packages but please do see the big picture: excessive dependencies ARE a problem, are they not? I do not think one can just dismiss it. postscript conversion SHOULD be possible even if some operations on Japanese fonts cannot be done. urw-fonts -> chkfontpath -> xfs chain can be broken too - perhaps chfontpath can be noop if there is no xfs installed? While I understand that foomatic needs some way to organize the data, I wonder what system-config-printer needs alchemist and libxslt for? To store own data - there is not simpler way to store few or even several hundred key-value pairs? It certainly does not need alchemist to parse or generate cups config files. I chose just a few examples but the the dependency list above is much longer.
