[SOLVED] Umask a specific directory

[funyotros]

Is there a way to umask only a specific directory?
I want that everyone who add a file in this folder gets its file moded 700. But that adding it in any other folder still moded as default.

Thanks in advance !

I've solved using access control lists. man setaclf

setfacl -d -m g:riskyusers:r mypreciousdir

Set read only perms to any new file created in mypreciousdir by a member of the riskyusers group.
