When building Features, i find it useful to keep a 'backup' of the full configuration and commit it to version control.
If something breaks when i package a feature after i test how it works by doing a full re-install of the profile that brings together the feature modules, i can restore things i missed from the configuration export.
Unfortunately, every site install produces different UUIDs in every configuration file, so i cannot use a diff to determine if there are missing or unexpected changes in the site-install version of the configuration i packaged up. Drush does not have an export option to strip UUIDs on export.
In the past we used a script to delete all the UUID lines, but not being built into Drush, it was Python or Bash i think, it was awkward to use. But if i find it i'll post it.
How can i get a clean diff of changes that filters out the noise of the UUID changes?
