Yes, it is the best thing to do on any version of OS X, since it
guarantees you won't end up with a partially installed or updated
kext if the system crashes at just the wrong time.


Is this also the procedure that should be followed when you install
your kext through a .pkg package? That would go against the idea
behind a .pkg.


This is in fact how the kext is installed. Following the installation,
the postflight script changes perms, etc and touches /S/L/E.

I don't understand why the postflight script would need to change the permissions, owners or groups. If they are correctly set in the pax/cpio archive, why would they need to be changed?

There used to be a bug in Installer.app on Mac OS X 10.2 where owners and groups were not correctly set if you needed to have root:wheel. And yes, in this case, you had to fix the owner and group settings in the postflight script. But this has been fixed since.

If you need to do some post actions to install something in /S/L/E when you conform to the recommended permissions and groups, it should be considered a bug in Installer.app, in the documentation or in the OS.
