From Mandriva 2008.1 (cooker), on EEE pc

Yup, installed Mandriva 2008.1 cooker (rc nearly 2) on my eee pc, and it mostly works, although I do have a few emails to send to cooker about problems, like the default selection of packages on CD1 for i586.

Compiz works ok, yet to find out how to allow windows to be moved upwards, as they tend to be too big for the screen.

how rpm delta's should work

Server consists of: rsync, cpio. - it should only have copies of the latest rpms on it. It does not need the other ones to create diffs, as that is done on the client. When server gets a request, it extracts the rpm, if not already extracted, into a temporary store. Then sets up an rsync server for the client. It also has a file with the md5sum’s of all the files, the pre and post scripts, and rpm info.


  • compares rpm file database of md5sums against copy on server.
  • copies files that are different into tempory spot
  • rsyncs the modified files from the server to the client.
  • gets the new pre and post scripts, updated md5sum list and info
  • builds itself a new rpm based on the contents of the old one, plus the changed files.
  • uninstalls the old rpm and installs the new one.

This should save significant bandwidth, be easy to implement, and use existing technology.
