When extracting directories, we should compare the mode of the existing and the mode of the one to be extracted, and probably spit a warning if they are different so the user at least knows this could be an issue. I am not sure which set of permissions to go with, however.

What do you mean in that last sentence ?

Should we assume the directory permissions in the package being installed are correct, or should we assume the permissions on the user's filesystem are correct?

Package: rw-r--r-- root root /foo Filesystem: rw-rw-r-- root fooey /foo

Which one do we go with?

Ah ok. Well Paul and Jeremy gave their opinion on this in the BR : http://bugs.archlinux.org/task/7484#comment17621 "It seems in general dangerous to change the permissions of existing directories by installing new packages, but it could break things either way." http://bugs.archlinux.org/task/7484#comment17623 "* directories are more likely than regular files to have user-modified permissions/ownership -- having pacman force update of permissions/ownership may undo something the user has carefully set up." And both suggested to print a warning in this case, and you agreed on that too ;)
