Look at the structure of the directories and the contents of the files in a Debian repository. Distributions are organized by code name in some places and by status name in others. Metadata files contain both code names and status names. The working programs expect this and it is hard coded into them. The repository is a database, but it does not have what RDB people call 'data independence'. Historically, the transition of a code name distribution was fraught with difficulty for all involved. The introduction of the pool helped a lot, but the system remains fragile. I love Debian, but the repository system, files, directories, and software is very complicated. To change the way distribution names are handles by *all* the software consistently will be a lot of work and nearly impossible to do either in one fell swoop, or gradually either. Just my opinion. I may be wrong. You can file a bug, if you want. Once I realized that the theory sections of the documentation are misleading, and only certain usages are given in the examples, I looked at the organization and decided the way it is is way beyond being fixed with a few intelligent suggestion by me, and nevertheless, good enough for me. If all the metadata about packages were kept in a proper relational database then all the various special purpose programs for answering various questions about what is in the repository could be replaced with SQL queries. The code-name/status-name issue would be recognized in the normalization and this issue would be resolved with finality. But it won't happen just by filing a bug, IMHO. -- Paul E Condon [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
