And I've shown that this "way" is wrong - having xattrs outside package

I want to get rid of SUID. If you know how to do this - please tell. The
only way I'm aware is by storing xattrs in rpm packages either directly
or by some mechanism bound tightly to upgrade procedure (I don't know
rpm internals if that's possible now).

So how can I store these caps in rpm? Or force rpm not to overwrite
these set by me in filesystem (manually or by other tool)?

I'm not referring to SELinux, it's overcomplicated for most of the
people. Unlike xattrs, which ARE contemporary replacement of ancient
file permissions (ACL) and authorization management (capabilities).
