I think `file` and `readelf` would help.
file is several times slower than readelf. But I have found some other optimization: * Only extract files from /opt /lib /sbin /bin /usr/lib /usr/sbin /usr/bin * run the script for both arches in parallel * treat links to libs and executables as files (this way we can check for exact so names) * The script uses results from previous runs and as a result should be fast enough to be run on gerolde (I can provide an inital data set) The resultsing db files are quite small: 20 KB for core and 320 KB for extra. So, what do you think about adding this to our cron jobs? We could run it on a daily base and update the db files. It should be easy to write clients which check for possible rebuild candidates and do all kinds of integrity checks. -- Pierre Schmitz, http://users.archlinux.de/~pierre
