POSIX file ACLs: is it possible to grant default read access for a specific user to new files/directories within a directory, without setting default ACLs for user::/group::/mask::/other::?
On a directory with the following permissions:
sudo setfacl -Rdm user:someuser:rx .
default:user::rwx default:user:someuser:r-x default:group::r-x default:mask::r-x default:other::r-x
In my specific use case this time, the default ACL is to ensure a backup user can access all the contents of the directory. However, a service creates a socket in the directory in question on start, and the other default ACL entries above result in that socket not being world-writable, which it needs to be.
Is there a way to set default file permissions for a specific user without affecting default file permissions otherwise?
