Most package managers with rpm support can use +the repomd style but urpmi can't. Only a few package managers support +synthesis style metadata. Switching to this 'standard' repository metadata +would give people more choice: use other package managers (e.g. yum or zypper) +in mageia and use urpmi on other distros. In the long term this should help +make urpmi easier to maintain: the "standard" metadata is a bit easier to +extend, +urpmi will be more a standard tool: behavior can easily be compared to other +package managers, test suites may be shared. + +Some not very useful index size numbers for mga cauldron x86_64 core/release : +1.7M synthesis.hdlist.cz +1M info.xml.lzma +5,6M changelog.xml.lzma +8,7M files.xml.lzma + +4,4M primary.xml.gz +3,4M other.xml.gz +11M filelists.xml.gz (8,8M when compressed with xz) + +Goals: +- no negative impact for people who use the default package tools +- basic support for other package managers (yum, zypper, apt) in mageia 2 + (better support where packagekit uses the package manager the user has + chosen is not part of this spec but could be a follow-up feature) + +the plan is: +- modify urpmi to only support repomd metadata +- add repomd metadata to the cauldron repository while keeping synthesis +- upload the new urpmi +- after either the mga2 or mga3 release: + drop synthesis/hdlist metadata from cauldron + +so there will be 1 or 2 stable releases that carry both types of +repository metadata.
