In the event of a symlink<->dir transition, the paths for the incoming package need to be resolved to match the filelist for installed packages.

Can you explain this to me? Every time I think I understand, I don't... e.g. outdated local package: /usr/foo -> /usr/bar/ /usr/bar/baz update sync package: /usr/foo/baz So /usr/foo/baz is a new file so it is tested for presence in the filesystem. But /usr/foo/baz "exists" on the filesystem as /usr/bar/baz.

From what I understand, you resolve the package file "/usr/foo/baz" to "/usr/bar/baz" and note that it is in the old package so not a conflict. Which feels wrong to me...

Can we do something like testing whether the directory of the "conflicting" file and the resolved path of that directory are different? If not, then we must be dealing with a case of a filesystem symlink being replaced with a package directory (otherwise the package directory would have conflicted with the filesystem symlink earlier).

Note: this only enables the symlink<->dir transition itself. Any installed packages with invalid file lists containing symlinks are not detected.

NO! We definitely should not...

Packages removed due to conflicts are always removed at the beginning of the transaction and as such can be included in the check for whether all owners of a directory will be removed in a transaction. Installed versions of packages being upgraded, other than the one with the conflict, cannot be used because our transaction ordering is not intelligent enough to ensure that they are removed prior to the installation of the conflicted package. Also, return false from dir_belongsto_pkgs on errors. Previously, we simply continued which could return true even if we were unable to actually establish that the package owned the entire tree.
