Beside the constricted usage of v4l2convert.so for e.g. normal shells and system programs like mount and ls this makes on systems having a own /usr partition that the /usr is busy during shutdown! Compare with bug #486710 IMHO this is a no-go and should be fixed not only for 11.1 and SLES11 but also for factory. Beside this: Michael? is there a way to switch off this preload for all processes used for shutdown, that is /sbin/init, the programs started by the boot script, and all other helpers. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

From source code rtld.c:
/* There usually is no ld.so.preload file, it should only be used for emergencies and testing. So the open call etc should usually fail. Using access() on a non-existing file is faster than using open(). So we do this first. If it succeeds we do almost twice the work but this does not matter, since it is not for production use. */ .. v4l2convert.so is not for emergencies nor for testing. But it can not be switched off in rtld.c. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Preloading is a really terrible but indispensable solution for many problems (e.g. in the v4l2 sector). Of course, it's the result of wrong driver/application/interface design, but that's another discussion... However, I agree that packages should not be allowed to enable permanent preolading (with ld.so.preload). I think a proper solution would be do let the build-service stop packages from doing that. The rest should be up to the user. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
