We have try to update the type of acl to merge two record without having the right of "delete" but with the right "edit".
We have find the solution to update in a non-upgrade safe manner by editing the file :
and by replacing the word "delete" by the world "edit", but we try to find a solution in a upgrade safe manner.
It seem that put this file in the custom directory do not seem to work.
Any one have an idea ?
