Carsten Ziegeler commented on SLING-6313:
-----------------------------------------
I'm not really sure if we should add a fix for when the .ser file gets
corrupted. If that file gets corrupted other stuff can get corrupted at least
in theory as well
And finally with the upcoming R7 spec, config admin will directly support an
alias and there is no need to for either storing the mapping somewhere or
adding internal properties to the configuration. This is already implemented in
Apache Felix
> Sling installer can duplicate factory configurations if an invalid
> RegisteredResourceList.ser is found
