What they choose to do with their distro should not affect the choices of any other distro. I see no reason for a /usr merge unless one is using Fedora or wants to turn their Gentoo installation into a makeshift Fedora installation. This merge should not be forced on Gentoo whatsoever. I would like to ask you to understand my intension. I believe that Gentoo is a distro that is famous for providing choises (USE flags and so on). /usr merge is also a choise, and I look for volunteers and supporters. BTW, /usr merge is not just a Fedora's caprice: is is done in Arch this year: https://mailman.archlinux.org/pipermail/arch-dev-public/2012-March/022625.html Sincerely, Alessio Ababilov Senior Software Engineer Grid Dynamics I'm completely in favor of choice, but only if it doesn't impede on any other choice(s). If /usr merges are completely optional and only tied to software that require it (read: systemd), then I'm fine. But requiring people to have an initramfs to boot a system that doesn't legitimately require it is silly. I don't even have /usr mounted separately, but there are many, many different system configurations out there and Gentoo is famous for supporting a wide variety. That variety is stomped on if something like a /usr merge is forced. It also makes building your default environment more complicated due to generating an initramfs. Arch is following Fedora as they consider them an upstream. They were one of, if not *the* first non-Fedora distros to ship systemd by default. They're a poor example. Really, Arch is just Fedora with a better package manager. ~Daniel

My company has 2 HP DL585 G5 servers and 5 Dell R... something servers. All using AMD processors. They currently are acting as XenServer hosts. How do I determine the 'least common denominator' for Gentoo VMs (running as XenServer guests), especially for gcc flags? I know that the (theoretical) best performance is to use -march=native , but since the processors of the HP servers are not exactly the same as the Dell's, I'm concerned that compiling with -march=native will render the VMs unable to migrate between the different hosts. A couple of points: * The effect of setting -march=native depends on the characteristics of the CPU (be it virtual or otherwise) * The characteristics of the vCPU are defined by qemu's -cpu parameter * qemu can emulate features not implemented by the host CPU (at a cost) One way to go about it is to start qemu with a -cpu model that exposes features that all of your host CPUs have in common (or a subset thereof). In that case, -march=native is fine because all of the features that it detects as being available will be supported in hardware on the host side. Another way is to expose the host CPU fully with -cpu host and to define your guest CFLAGS according to the most optimal subset. If you are looking for a 'perfect' configuration then this this would be the most effective method, if applied correctly. AFAIK, that's how XenServer configured its hosts. There's CPU Masking option when a heterogeneous pool of hosts were created, but I have the impression that CPU Masking is only being employed by the 'xe toolstack' (CloudStack) layer to determine to which host a VM can be migrated. Irrespective of the method, by examining /proc/cpuinfo and using the diff technique mentioned by Bruce, you should be able to determine the optimal configuration. Finally, in cases where the host CPUs differ significantly - in that native would imply a different -march value - you may choose to augment your CFLAGS with -mtune=generic to even out performance across the board. I don't think this would apply to you though. Certainly doesn't apply to me. Based on tech spec I have on the servers, the processors are very similar... I just want to be doubly sure :-) Thanks for the explanation (including the difference between 'march' and 'mtune' in your other email)! Rgds, --

[gentoo-user] How to get video output in the same window as the interface
Hi all, I just did an emerge world and now my vlc interface has gone feral. Previously a double click on a video would bring up one window with the video in the centre and the controls surrounding it, play, stop, progress bar etc. Now when it starts up, I get two windows, one that contains the controls and a black rectangle with the vlc witch's hat in the middle and another with the video playing. I've tried all sorts of options but can't seem to find the right combo - I probably can't see the wood for the trees after playing around with it so much. Does anyone have any idea what the config option is so I can bring things back to how they were? Any thoughts greatly appreciated, Andrew

Thank you! The next council meeting will vote if separated /usr without and initramfs is officially supported by Gentoo; I hope this time around finally is officially and unequivocally stated by the council that a separated /usr without an initramfs is *NOT* supported. As I see from http://www.gentoo.org/proj/en/council/meeting-logs/20130813.txt, the council has stated that it is not supported anymore. Well, better late than never. It was about time. The usr-merge will be a slow, gradual change; it will probably take years. The systemd package entered the tree in June 2011, after more than a year in an overlay, and then it took more than two years to make it an official alternative to OpenRC. The /usr merge will take a similar amount of time, if not longer. And when we are at it, why not rename '/' to 'C:\' ? Good one! :) I guess this merge happening only because systemd... Now the council expects people to: 1. maintain initramfs, it can be complex or simple task, depend on the configuration. 2. place all disk and filesystem recovery utilities within initramfs. 3. or... prepare to use rescue cd every time something is broken. Unclear why exactly we do have support in separate /usr. Regards, Alon

Let's see how it turns out... if Linux userspace will become like the Windows user space, then freebsd suddenly looks very promising alternative. Regards, Alon I've considered this as well. It's simply beyond me why so many people are willing to drink the kool-aid from a *single upstream* and let them shape the entire GNU/Linux landscape. It's one thing to support an *option*, but quite another to *force* users to use this option. Systemd itself doesn't look to be forced yet, but if the requirements for it are forced onto users, forcing systemd afterwards would be child's play. I saw this in action when I used Arch. It started with bash functions in their init scripts calling some systemd tools. Then the /usr merge. Eventually systemd itself was pushed. I'm beginning to lose confidence that Gentoo will avoid the same fate as Arch. Even Debian is falling to the systemd crowd. If this keeps up, it's only a matter of time before systemd infects every Linux-based distribution and BSD will be the only major free OS to avoid it. Red Hat may end up digging its claws into the kernel itself. What will protect the Linux landscape, if not distros like Gentoo that supposedly support user choice? Will all users who give a damn be forced to run LFS or Slackware if they wish to use Linux as their kernel? Maintain their own portage|pacman|deb repos and keep systems free of systemd? Where does the madness end?

I think it's a great experiment, but perhaps too much work for little gain, at least currently. I tend to agree. And I still wonder why it's called /usr merge if it only affects /bin and /sbin. If it's really a merge, shouldn't /lib also be affected?
