Hello Christian (and tons of Packaging Thanks! :), same issue here.
Turns out this line > Shell: /bin/sh linked to /bin/dash was the most important one in your report. When using dash, _EVERY_ _SINGLE_ _PROCESS_ as spawned by dash from within that kvm-launched kvm-ifup script ends up as defunct == zombie. I finally got that Aha! moment when kill -9'ing the currently stuck process and fortunately realizing that it proceeded with executing the subsequent shell line script process and got stuck again. dpkg-reconfigure dash, reverting to bash (which I normally never do, since it's all working perfectly fine provided one knows to avoid bashisms - devscript package's checkbashism script - in custom scripts) finally makes it work again. So, I don't know _why_ on dash it gets stuck (possibly due to specific shell execution environment limitations as imposed by kvm startup??), but IMHO such a strange issue should be investigated ASAP (also since dash appears to be the new default). Myself, I'm executing kvm as non-root user, BTW (not sure at all whether that actually makes any difference here, though). Side note: Gooooaad, I really hate having to experience odd little thoroughly annoying kvm setup quirks on almost every friggin' single ยง%&damn kvm upgrade I do. Oh well, at least _this time_ again it's working again ;) HTH, Andreas Mohr -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
