Simply check the last couple of lines of your update output to see what apt-xapian has to say. I am particularly looking for any cases where the updater would report database corruption or you think that it takes too long or causes too much disk access. Generally speaking the updates are conducted incrementally so they should be relatively fast. Assuming apt-xapian works as well as I believe the hook will only slow apt-get update down a bit (<10 seconds on most systems I'd say). example output: .... Hit <a href="http://ppa.launchpad.net" target="_blank">http://ppa.launchpad.net</a> utopic/main i386 Packages Reading .desktop files from /usr/share/app-install/desktop/: done. Reading Xapian index: done. Updating Xapian index: done. Reading package lists... Done In case you wondered about the command.... the final hook command I would actually imagine to set appropriate IO niceness and fork so that it doesn't block apt-get update at all and doesn't otherwise interfere with system usage but for this test I'd like it to be as prominent as possible. Also, I doubt this epic will land before 15.04 because ideally it'd be done globally for all of ubuntu if at all possible.
