[arch-projects] [mkinitcpio] mounting /usr from the initrd
by Tom Gundersen 02 Aug '11

02 Aug '11

Hi guys, I have been thinking about sorting out /usr being a separate mountpoint. Mainly because I keep getting bug reports that turn out to be caused by this. The current status is that we move some tools from /usr to / in the hope that this will allow us to boot without /usr being mounted. This mostly works, but not quite, as there are still stuff left in /usr that are used by early boot (and mostly just fails silently). This website created by the systemd folks sums it up nicely (just replace "systemd" with "initscripts" everywhere): <http://www.freedesktop.org/wiki/Software/systemd/separate-usr-is-broken>. The solution they propose, and which I agree with, is to mount /usr from the initrd just as we mount / (an alternative solution is to just declare separate /usr as not supported, but I guess that would not make us popular). Before working up a patch, I wanted to hear if there are any objections to this approach, and in particular that Thomas agrees that it is the right way to go. The interface I suggest is to allow two new kernel options "usr" and "rootflags" that correspond to "root" and "rootflags". The pivot_root stuff I submitted recently will already take care of unmounting. The syntax could obviously be discussed, and I suggest getting in touch with the dracut guys to make sure we choose the same syntax (I don't think they yet have support for this, but I might be wrong). Any thoughts? Cheers, Tom PS A nice sideeffect is that once we have this we can simplify a lot of our PKGBUILDS as they never need to put stuff in / any more, and eventually /bin, /sbin and /lib will be empty and can just be symlinked to /usr/{{,s}bin,lib}.

[arch-projects] [mkinitcpio] boot times with different COMPRESSIONs
by Tom Gundersen 01 Aug '11

01 Aug '11

Hi guys, We have a lot of compression options now for mkinitcpio, so I figured I'd try to measure which one gives us the fastest boot. I guess boot speed is the most important metric when deciding which one to choose. The measurements were done on an Lenovo ThinkPad x60, with an Intel Core 2 processor and an 5400 rpm HDD, so your milage might obviously vary. Here are my numbers: xz Startup finished in 710ms (kernel) + 2526ms (initrd) + 14335ms (userspace) = 17572ms Startup finished in 610ms (kernel) + 2448ms (initrd) + 48159ms (userspace) = 51218ms Startup finished in 710ms (kernel) + 2458ms (initrd) + 11294ms (userspace) = 14462ms Startup finished in 720ms (kernel) + 2488ms (initrd) + 12271ms (userspace) = 15480ms Startup finished in 710ms (kernel) + 2446ms (initrd) + 9602ms (userspace) = 12758ms gzip Startup finished in 560ms (kernel) + 2422ms (initrd) + 9917ms (userspace) = 12899ms Startup finished in 560ms (kernel) + 2445ms (initrd) + 9734ms (userspace) = 12740ms Startup finished in 560ms (kernel) + 2451ms (initrd) + 10544ms (userspace) = 13556ms Startup finished in 560ms (kernel) + 2427ms (initrd) + 9756ms (userspace) = 12744ms Startup finished in 570ms (kernel) + 2439ms (initrd) + 9823ms (userspace) = 12832ms bzip2 Startup finished in 810ms (kernel) + 2428ms (initrd) + 9690ms (userspace) = 12928ms Startup finished in 810ms (kernel) + 2448ms (initrd) + 9635ms (userspace) = 12893ms Startup finished in 810ms (kernel) + 2504ms (initrd) + 10212ms (userspace) = 13526ms Startup finished in 810ms (kernel) + 2445ms (initrd) + 8838ms (userspace) = 12094ms Startup finished in 820ms (kernel) + 2438ms (initrd) + 9613ms (userspace) = 12871ms lzma Startup finished in 790ms (kernel) + 2441ms (initrd) + 9335ms (userspace) = 12567ms Startup finished in 790ms (kernel) + 2442ms (initrd) + 9662ms (userspace) = 12895ms Startup finished in 770ms (kernel) + 2432ms (initrd) + 10199ms (userspace) = 13401ms Startup finished in 770ms (kernel) + 2425ms (initrd) + 9922ms (userspace) = 13117ms Startup finished in 770ms (kernel) + 2435ms (initrd) + 9502ms (userspace) = 12708ms lzop Startup finished in 550ms (kernel) + 2461ms (initrd) + 10730ms (userspace) = 13742ms Startup finished in 570ms (kernel) + 2421ms (initrd) + 20680ms (userspace) = 23671ms Startup finished in 550ms (kernel) + 2435ms (initrd) + 8752ms (userspace) = 11738ms Startup finished in 570ms (kernel) + 2454ms (initrd) + 9575ms (userspace) = 12600ms Startup finished in 550ms (kernel) + 2453ms (initrd) + 8540ms (userspace) = 11543ms Cheers, Tom

[arch-projects] [PATCH 1/2 mkinitcpio] shutdown: add a shutdown hook
by Tom Gundersen 01 Aug '11

01 Aug '11

Enabling the shutdown hook and using systemd v31 (which is yet to be released), means that on shutdown the root will be pivoted to /run/initramfs, from where the rootfs and all its submonuts (such as /usr) are unmounted cleanly. The same functionality will be supported in a future release of initscript. A natural next step is to add an "/usr"-hook, which mounts the /usr partition (if it exists) in the initramfs, so initscripts (and systemd) can always rely on it being mounted, and we no longer need to move some binaries/libraries to /bin, /sbin and /lib (as this does not work well at the moment). One might argue that this functionality does not beling in mkinitrd. The reason I propose it for inclusion here is: - it is independent of initscripts, so does not really belong there either. - in the future one might imagine extending this to integrate more tightly with the rest of the initramfs (e.g. store state/logs in /run/initramfs to ease debugging, or add shutdown-hooks, to go with the boot-hooks, to gracefully tear down things such as dm or nfs mounts at shutdown). - by behaving like dracut, integrating with systemd became trivial, and IMHO there is no point in systemd/initscripts/dracut/mkinitrd differing at the interface level.
