FILESYSTEMS (the default early_late_divider): 1. Move sysctl to run first 2. Move as many BEFOREs to REQUIREs as possible. 3. Minor effect, move hostid_save from right before mdconfig to right after. A lot of the early scripts make use of sysctl one way or another so running this first makes a lot of sense given that system-critical values are often placed in sysctl.conf. My original purpose for working on this was that while doing some debugging on other stuff I noticed that the order of execution was different in the first pass through the early scripts and the second. In practice that doesn't matter because the scripts are not executed the second time. However this _can_ result in problems if the difference in the rcorder moves a script from the late section to the early section in the second pass (which would mean the script would not get executed). So, I wanted to make the order of execution of the scripts in the early section more deterministic. In the course of debugging the ordering problems I noticed that moving the BEFOREs to REQUIREs prevented the changes in order from the first pass to the second pass without having to make any substantial changes. (Of course it's no secret that I think BEFORE should be avoided as much as possible, but this is a good example of why.) Reviewed by: silence on freebsd-rc@ MFC after: 8.1-RELEASE
