[OS X Emacs] Synchronizing customizations/preferences/configs between computers

[Hendrik Visage]

Hi there,

 I constantly runs in this problem that I made change on my desktop,
my laptop or my home computer, and/or then installs a new machine and
then missed the changes I've made elsewhere.

 If I make use of DropBox/OwnCloud for file synchronization between
computers, what wouldbe the best method to have these
changes/customizations/preferences synced between the computers?

 What method(s) are others using for this? especially when
(re)installing a machine?

Thanks
Hendrik
