OK, good, that was my thought too. In fact getcap/setcap are actually in libcap2, not attr (I'm an idiot), but that's also tiny. getfattr/setfattr are more general and seem to have a more convenient interface from d-i's point of view, though. The main thing to take care about will be to make sure that we don't fail to install if the target filesystem doesn't support extended attributes. I think this will unfortunately mean that /bin/ping won't have its setuid bit restored, at least not without lots of special-casing, but that's still better than a failed install. -- Colin Watson [[email protected]] -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
