Any program that updates a file and in so doing alters the
security mask or deletes any ACL's or extended attributes of that file
is intrinsically broken.

If I have a source file to which I have assigned an ACL permitting
another specific user to access the file, that ACL *must* stay in
place. Likewise, if I have set a security mask to keep other users in
my group out of a file, i.e. 0600, that security mask must be
preserved.
