Discuter:Speedboot

De Wiki de la communauté Mandriva.

Je me suis permis de remanier la section "Que fait speedboot" qui s'apparentait plus à du "petit nègre" (j'ai horreur de cette expression mais on la comprend...) qu'à un article sérieux. Comme c'est la première chose qu'on lit sur speedboot, autant que ça soit clair et français, quitte à paraître imprécis, non ?

Hi folks,

those of you who follow changelog might have noticed I did a typo in latest initscripts changelog : I wanted to say "speedboot is now in automatic mode" and I wrote "speedboot is not in automatic mode".

Anyway : speedboot is now automatically enabled on all systems, using the following heuristic : - first boot on a specific kernel version : speedboot is disabled and boot will be checked to see if some conditions are preventing speedboot to be enabled - second boot on the same kernel version : if conditions where met, speedboot is enabled and status is saved. - if speedboot failed, it will be tested a second time (for instance, if you had a dkms issue, stuff like that) for the next boot and either disabled for this kernel version (if failed) or enabled back. - speedboot will autodisable if network authentication is enabled or if runlevel is not 5 - to disable or force speedboot, you can change its default in /etc/sysconfig/speedboot or to do a one time change, use "speedboot=yes/no/auto/probe" on kernel command line.

speedboot=probe is used to reset status for a specific kernel version (and redo the check).

status for speedboot is readable in /var/lib/speedboot/status

The only missing things in speedboot are : - test disk speed to enable or not readahead (it is always enabled but will slow things on slow harddisk). - tune readahead "split" between first and second phase and maybe force readahead collection when speedboot has been enabled back.
