However, note the funny part here- if we sync our DB entries, and then your machine gets powered off, you might end up with a DB that got committed but files in the package never actually got written to disk.
Do we know that for sure? It depends on how libarchive is written, right?
This is interesting. I think we just need to make sure that the meta data are written and the pacman.log. So, if something fails during a transaction the user could reinstall the packages manually. OT: I have read that Sun uses ZFS snapshots to implement transcation in their package manager. Doing this on FS level seems to be the only sane way imho. Its hard to revert the changes of an install script from pacman's point of view. -- Pierre Schmitz Clemens-August-Straße 76 53115 Bonn Telefon 0228 9716608 Mobil 0160 95269831 Jabber pierre@jabber.archlinux.de WWW http://www.archlinux.de
