sync

Keeping preferences and similar stuff (e.g. password files, bookmarks) in sync between two different Linux distributions (unison)

Thus I only share /home/user/Documents among the distros and have separate /home/user/.preference files, some of which I syncronize during shutdown.
This is the /home/user/.unison/shared_resources.prf file:
