yum has the protect-packages plugin.

It does more or less what you mention above.

It's not installed on my RHEL-clone system. I don't have a useful Fedora system at present, so I can't check that.

Unless yum-protect-packages is part of the standard set of installed packages, it's not going to be very effective.

I see a lot of yum plugins listed but uninstalled, I don't know what most of them do. Perhaps more of them should be installed as part of the base installation, and users directed to configure them.

If you install the protect-packages plugin with base it plays hell with things like mock and chroot construction - which is part of the reason it is not installed in base. We can work around it - but we've not had much demand for it.

And considering the lack of detail here I don't see that demand increasing overly much.

If you wish to have this protection then you can install it. It's pretty simple.

If you want to know more about what the plugins do I would recommend the 'info' command to yum.

for example:
$ yum info yum-plugin-protect-packages
Name       : yum-plugin-protect-packages
Arch       : noarch
Version    : 1.1.23
Release    : 1.fc11
Size       : 12 k
