Are there no plans to support POSIX ACLs in Linux filesystem ?
Of course, it requires patched kernel source, but enables more

From a rather quick look at it:
The client requests a change in the (NT) acls
his interface allows for. Samba recieves this,
plops it into a structure that can represent a
superset of NT's acls and passes it to a
filesystem-specific module to implement.
In the common case, the only things you can change
are uwner, grou pand other permissions, as
this is all UFS provides.
The result is then returned to the client in
NT-speak and it updates it's idea of what was changed.
