As someone campaigning +to keep /usr on a separate partition, I'd have thought this was what you +were trying to protect against in the first place... it seems totally +contradictory to suggest this as a solution. + +Keep in mind that one of the key aims in highlighting this issue via +systemd is to actually ALLOW /usr to be a useful and self contained +filesystem. If /usr is properly configured without leaking half of it to +/ it could be shared across multiple machines far more easily or even +mounted as ro by default which could prove handy for security. Again, +this is about highlighting the issues with an aim to making /usr much +more useful. This is a laudable aim but you seem to be shooting it down +due to gut reactions and prejudice.

You're not +giving ANY technical arguments here, just spouting FUD and pointless +rhetoric which is not something I would expect to see from yourself :( + +>>>>><i> That's just plain idiotic. +</I>>>>><i> I somewhat agree.

By this argument if you were to build a house upon sand, it +would be the fault of the brick manufacturer for building too heavy +bricks, not the planners who thought that sand was an appropriate +foundation. Papering over the cracks is not good for anyone. I want a +robust system by design, not by careful manipulation of the fundamental +problems to avoid the known broken bits. + +><i> For those people that are so concerned about bootup times, why dont +</I>><i> they buy new hw, use fast ssd and learn how to suspend to ram/resume ... +</I> +I really don't understand why people keep harping back to "startup +times" as the sole argument for a systemd-based system. It seems to show +a lack of understanding of the project as a whole if this is the only +justification used. + +Sure better h/w will help boot times and I certainly want them myself, +but it doesn't mean I don't want systemd. I want proper process +supervision, I want logging all the way from early boot, I want +information about why a service failed and I want to be able to track +when binaries are launched from webservices and run away (either +malicious due to a breach or just bad programming), and I want to +properly unmount / and deactivate LVM on shutdown and reboot. I cannot +do any of this with sysvinit but systemd means I can do all of that and +more. + +>><i> If you have constructive criticism as to the reasons why this is now +</I>>><i> warned about specifically in systemd, then this is perfectly valid but +</I>>><i> should be done in context rather than simply calling it "idiotic" +</I>>><i> without any further clarification. +</I>>><i> +</I>><i> +</I>><i> Well, it _is_ idiotic if it breaks working setups / possibilities to +</I>><i> finetune systems. +</I> +It depends on your definition of "working". Sure if you specifically +work around the know limitations of the design then you may get a +bootable system, which you could classify as working, but I wouldn't say +this is a robust base. Just a house of cards waiting for the next +failure. I'd rather try and address the problems properly and be frank +about it in the discussions. + +>><i> And systemd is not saying that /usr cannot be on a separate partition. +</I>>><i> It's just saying that it cannot realistically be the job of the init +</I>>><i> system to mount it, it has to be handled at early boot in the initramfs, +</I>>><i> not by init.
