Hi guys, On machines using lvm, the lvm service must pull in udev-settle.service. However, most other services don't need to wait for udev to settle. By removing Before=basic.target from udev-settle.service I can speed up boot on my machine by about two seconds. A side-effect of this is that it no longer makes sense to enable udev-settle unconditionally. However, it would anyway be a bad idea for a service to assume udev-settle to be enabled, so all services that needs to wait for settle (such as lvm and sysv compat units) should anyway make this explicit. What do you think? Cheers, Tom >From cd8413fa7defa94b7e6fa093626a142bb2788391 Mon Sep 17 00:00:00 2001 From: Tom Gundersen <teg@xxxxxxx> Date: Fri, 6 May 2011 15:19:08 +0200 Subject: [PATCH] settle: do not block basic.target Some services (such as lvm) stil need to wait for udev to settle. However, there is no need for all other services also to be blocked. This means that it is no longer possible to enable udev-settle.service unconditionally, but every service that needs it must depend on it explicitly.
