Of course this is one way to find bugs in packages. But what about the
documented (in German) case where
- after fresh installation, reboot (ok) and updates right after
installation I was presented with a list of more than 100 "orphans".
- I ran 'urpme --auto-orphans' and rebooted
- several system services (which started successfully after
installation) refused to start now because of missing files
Of course urpmi was not the culprit because it only checks
dependencies. But that did matter in that situation. The auto-orphans
function obviously listed packages which may have no dependencies but
are needed by the system. That's why I do not complain about urpmi but
about the whole function. As long as this function is only based on
package dependencies it is not safe to use it.
