The only possibilities I see quickly are using chattr and/or acl lists
(seems more promising, but not sure as I didn't take the time to really
understand the *implied* results).
$ man -k acl
acl (5) - Access Control Lists
acl (rpm) - Access control list utilities.
chacl (1) - change the access control list of a file or
getfacl (1) - get file access control lists
libacl (rpm) - Dynamic library for access control list
setfacl (1) - set file access control lists
A *brief* scan doesn't yield an obvious simple solution though. But as
mentioned, there may be some implications that might "git 'er done".
