Adjusting permissions of directories in their install scripts results in warnings such as the following when the package update:

warning: directory ownership differs on /var/lib/postfix/ filesystem: 73:0 package: 0:0

If the package being installed is the only owner of the directory, update the directory's permissions to those in the package file.

This also allows directory permissions for a package to be changed directly in the PKGBUILD file rather that requiring adjustment in an install scriptlet.

This does require searching through all installed packages filelist to see if any other directories own this file, which does create a slowdown in these error cases. Once the ability to use symbolic names for owners is added, this code path will run only if there is an acutal error or in the rare case that directory permissions are genuinely being changed.

Packages can currently avoid this being run by reverting their directory permission changes in pre_upgrade().

I'd like to push this to maint if people agree. These "false" warnings are causing too many issues.

So what can the user do if they changed it themselves and want different permissions than what's in the package?

The same thing as always... Add it to NoExtract A
