Fun times

without comments

So, this past weekend I have spent countless hours trying to get our college Mac labs backup and running due to an update that I pushed out on Friday.  Of course, most of you are probably like, “Didn’t you test it”.  Of course I did, the one thing I did not test was a double restart of the system.  After debugging and debugging we could not figure out what the update did that caused the stations to not boot (Basically grey apple logo with spinning wheel).  So, only solution we had at the time was to reimage everything.  Fun… not so much.

Apple’s wonderful debugging and verbose modes were useless, especially since the machines would only boot as far as Single User mode.

We tried to 777 the whole drive to see if that would fix the problem, no go.  We knew it was permissions related, but what?

Thanks to FileWave, the problem was found.  Leopard requires the following permission on /System/Library/LaunchDaemons, 755.  In the FileSet I pushed, the permissions where set to 775.  This is where you start scratching your head. Why should that make a difference……?

Anyways, this is a good thing to know.  Oh, Apple’s own Repair Permissions utility fixes permissions inside this folder, but not the folder itself.  WHY!!  Thanks to Jay and the whole CIAS crew with helping to get our area back up and running.
