tetex-font-cm-lgc - package scripts are using wrong config file
Last modified: 2007-11-30 17:11:16 EST
Description of problem: %pre and %post scripts need to make sure that updmap.cfg is the one which is listed by 'texconfig-sys conf' on the original installation and which is marked as %config by rpm. Otherwise they create a new, independent, updmap.cfg in some directory which depends on changeable ordering in $TEXFONTMAPS variable. In other words a postinstall scriptlet should be like this: /usr/bin/texhash if [ "$1" = "1" ]; then /usr/bin/updmap-sys --cnffile /usr/share/texmf/web2c/updmap.cfg \ --quiet --nohash --enable Map=cm-lgc.map fi and postuninstall one if [ "$1" = "0" ]; then /usr/bin/updmap-sys --cnffile /usr/share/texmf/web2c/updmap.cfg \ --quiet --nohash --disable cm-lgc.map fi /usr/bin/texhash Version-Release number of selected component (if applicable): tetex-font-cm-lgc-0.5-5.fc5 but this equally applies to tetex-font-cm-lgc-0.5-5.fc4 How reproducible: always and creating updmap.sys is messing up a system as the first found updmap.sys is used so cleaning that up requires not only removing such extra configuration files and rerunnig, with a correct configuration file, updmap-sys for all extra packages with configuration written in a "wrong" places. Nasty and I do not see a good way to make that automatic.
I believe this is a bug in tetex. texconfig-sys conf specifies TEXMFSYSCONFIG=/usr/share/texmf-config, and that is where updmap.cfg should be located. The marking of /usr/share/texmf/web2c/updmap.cfg as config is an rpm specific thing which should also be changed. I opened a bug against tetex (bug #172507) and will wait to see the reaction before closing this.
I am afraid that regardless if bug #172507 is indeed bug or not you have to deal with a buggy software from time to time. The problem is that you have simple ways and ready options to work around this bug but you are refusing to do that. This puts this bug squarely in your lap as even if things get fixed in other ways there will be buggy systems around for quite some time. If you want to play it safe then you should modify your scripts in this way: /usr/bin/texhash cnffile="$(texconfig-sys conf | grep updmap.cfg)" if [ "$1" = "1" ]; then /usr/bin/updmap-sys --cnffile ${cnffile} \ --quiet --nohash --enable Map=cm-lgc.map fi I agree that a behaviour of updmap-sys is buggy and what it does in a modified script should be a default behaviour. No matter what it should not quietly change how a system is configured; but before it gets fixed, if ever, there is no point of compounding the bug especially if you have trivial means to alleviate its presence.
Given the discussion in bug #172507, it looks like an interim solution could be to use a run-time configuration file. It seems also safe both for systems which do and do not have tetex-font-cm-lgc installed. I will update the spec file as suggested in comment #2. Thanks
