Quick ACL question:

I want to set up default permissions for a file share so that everyone can rwx all of the directories and so that all newly created files are rw. Everyone who is accessing this share is in the same group, so this isn't a concern. I have looked at doing this via ACLs without changing all of the users' umasks and such. Here are my current invocations:

setfacl -Rdm g:mygroup:rwx share_name
setfacl -Rm g:mygroup:rwx share_name

My problem is that while I want all of the newly created sub-directories to be rwx, I only want newly created files to be rw. Does anyone have a better method to achieve my desired end-result? Is there some way to set ACLs on directories separately from files, in a similar vein to "chmod +x" vs. "chmod +X"?

Thanks
