The update candidate has to contain a marker file .installation/.update.txt with revision matching current installation's revision. Any update files from updateDir are copied to installationDir. If any of the updates (apart from system-paths) conflict with user changes, the user changes are preserved and the updated file is added with '.glnew' suffix.

Returns:

list of solved FileConflicts

Throws:

org.jboss.galleon.ProvisioningException - - if unable to apply the changes from updateDir to installationDir

InvalidUpdateCandidateException - - if the folder at updateDir is not a valid update

MetadataException - - if unable to read or write the installation of update metadata
