I spent Monday and tuesday this week in London with a lot of the -people involved in the boot system on Debian and Ubuntu, to see if we -could find more ways to speed up the boot system. This was an Ubuntu -funded -developer -gathering. It was quite productive. We also discussed the future -of boot systems, and ways to handle the increasing number of boot -issues introduced by the Linux kernel becoming more and more -asynchronous and event base. The Ubuntu approach using udev and -upstart might be a good way forward. Time will show.
- -Anyway, there are a few ways at the moment to speed up the boot -process in Debian. All of these should be applied to get a quick -boot:
- --
-
-
- Use dash as /bin/sh. - -
- Disable the init.d/hwclock*.sh scripts and make sure the hardware - clock is in UTC. - -
- Install and activate the insserv package to enable - dependency - based boot sequencing, and enable concurrent booting. - -
Support for makefile-style concurrency during boot was uploaded to -unstable yesterday. When we tested it, we were able to cut 6 seconds -from the boot sequence. It depend on very correct dependency -declaration in all init.d scripts, so I expect us to find edge cases -where the dependences in some scripts are slightly wrong when we start -using this.
- -On our IRC channel for this effort, #pkg-sysvinit, a new idea was -introduced by Raphael Geissert today, one that could affect the -startup speed as well. Instead of starting some scripts concurrently -from rcS.d/ and another set of scripts from rc2.d/, it would be -possible to run a of them in the same process. A quick way to test -this would be to enable insserv and run 'mv /etc/rc2.d/S* /etc/rcS.d/; -insserv'. Will need to test if that work. :)
+Aftenposten +melder på forsiden av webavisen sin at de tror Erling Fossen +provoserer nordledinger med sine uttalelser på +fotballtinget. Jeg er utflyttet nordlending, og må innrømme at jeg +ikke kjennet så mye som et snev av provokasjon fra denne litt morsomme +uttalelsen til Hr. Fossen. Lurer på om Aftenposten har noen kilder +utenom redaksjonen for sin påstand om at nordledinger er provosert av +Hr. Fossen. Må innrømme at jeg tviler på det.
+ +Det hele bringer tankene tilbake til Sture Hansen i Hallo i Uken.
