Re: [Bug 829628] Re: [FFE] Add cgroup-lite package
Hi Serge, On Thu, Aug 25, 2011 at 04:23:25AM -, Serge Hallyn wrote: Quoting StefanPotyra (stefan.pot...@informatik.uni-erlangen.de): Thanks for looking, Stefan. This looks odd: +cd /sys/fs/cgroup +for d in `/bin/ls`; do + umount $d || true +done Thanks for drawing my attention to this. This is indeed a problem. As an example, I did: (as root) mount --bind /dev/pts /mnt (as serge) (cd /sys/fs/cgroup; ln -s /mnt) (as root) umount /sys/fs/cgroup/mnt and /mnt got umounted. I didn't think about such a scenario, and believe that that would be the fault of the admin to mount stuff there. As for the for d in `/bin/ls`; do bit, what exactly looks odd about it? I do it all the time by hand, but that doesn't mean it shouldn't be changed here... I usually use for i in *; do ;) The case where * doesn't match anything should be covered by || true, right? Anyways, I guess I wasn't clear that this was just a small oddity, not at all a blocker. I had considered specifying a (configurable) list of cgroups to mount, and then only umount those. I.e. CGROUPS=memory devices cpu freezer at top of the upstart job. Maybe 'all' option which then grabs all from 'cat /proc/cgroups. Would that be preferable? I like the current simplicity :). However that's up to you, I'd be equally happy with it. Is the following sufficient (no clue really, I've never been too intimate with upstart scripts)? +start on mounted MOUNTPOINT=/sys The cgroups get mounted under /sys/fs/cgroup, and have no userspace dependencies, so it should be sufficient. Having /proc mounted? (Is it guaranteed to be mounted prior to /sys?) Having /usr mounted in case it is on a different partition? (Or don't we support such a scenario). As I wrote, I don't have too much clue about upstart. apart from that, I don't see if any mentioned bugs have been forwarded to upstream. Can you shed some light here please? Seeing upstream The bug about cgclear failing (so that the job fails to stop, and the package can't be removed) was mentioned upstream, but I don't believe they've pushed a patch for it yet. They announced in the last few days that they expect all functionality to be pulled into systemd, and therefore will stop developing. Ah, ok. IMO it's both boot speed and not running extraneous daemons on your system. Go ahead then, FFe granted.

[Bug 481604] Re: konqueror and arora show jpgs incorrectly
Hi, as has already been asked, can you reproduce this on real HW? While the driver is not perfect, the emulation of the graphic hardware in kvm is much less than perfect. Hence I assume that the probability is higher that it's a bug in kvm, reassigning. If you come to the conclusion, that it's a driver bug after all, please reassign (there's lot of speculation for this bug, and I just added some more ;)), Cheers, Stefan. ** Package changed: xserver-xorg-video-cirrus (Ubuntu) = kvm (Ubuntu) -- konqueror and arora show jpgs incorrectly https://bugs.launchpad.net/bugs/481604 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to kvm in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
