everyone, hello! I want to edit comps.xml which is included in Fedora core 1 in order to install my own rpm packages when installing Fedora. I did things described below, first,i copied my own rpm packages into the directoy "rpms" which resides in the Fedora installing directory. second,i added the group section of my own into the comps.xml.The content is as follows: <group> <id>my_group</id> <name>My Own Group</name> <description>MY Own Group</description> <uservisible>true</uservisible> <grouplist> <groupreq>base</groupreq> </grouplist> <packagelist> <packagereq type="default">gd</packagereq> <packagereq type="default">perl-GD</packagereq> <packagereq type="default">perl-GDGraph</packagereq> <packagereq type="default">perl-GDTextUtil</packagereq> <packagereq type="default">mrtg</packagereq> <packagereq type="default">rrdtool</packagereq> </packagelist> </group> third,i added the corresponding content to the section of gruophierarchy.The related content is as follows: <grouphierarchy> ... <category> <name>Servers</name> <subcategories> ... <subcategory>my_group</subcategory> </subcategories> </category> ... </grouphierarchy> But when i install the Fedora,i see nothing in the box "select the optional packages to be installed" except for gd and mrtg which is originally included in Fedora.I guess i must have left out some important steps. Please help me.This is the first time i use Fedora.Or you can tell me some docs which can help me solve my problem.Thanks anyway. mosquite
