Package: hal Version: 0.5.11-3 Tags: patch User: [EMAIL PROTECTED] Usertags: origin-ubuntu intrepid ubuntu-patch
Hi! It already occurred several times to me that people had trouble with FDI files which were apparently not "picked up" by hal. One particular case is https://bugs.launchpad.net/bugs/275825, where I finally saw the light: time-based comparison of .fdi files vs. the cache, as done in di_cache_coherency_check(), doesn't work with dpkg, which maintains the original file timestamps on unpack. The quick fix for this is to remove the cache in the init script, which I just did in Ubuntu (we are close to release). It sacrifices most of the startup speed improvement unfortunately, and hal still won't pick up fdi changes immediately, but at least it will work after a reboot. The more correct long-term solution could be to create a dh_install_hal_fdi which generates /usr/lib/hal/hald-generate-fdi-cache postinst snippets, and convert all packages shipping .fdi files to use it. But that's not really adequate for Lenny, and with DeviceKit being on the horizon, it might be obsolete before we even finish..
