"persistent" RPMs

"persistent" RPMs

[Yuri Csapo]

Does anybody know how to instal an RPM on a RH-derived system and make it persistent so that future 
upgrades don't replace them?

Gerardo, thank you for your reply.

I do appreciate the problems of holding something back. While I understand this situation is not 
sustainable in the long term, I don't see why I shouldn't be able to hold back a particular package, 
of course in the process holding back all its required and dependent packages, while letting other 
parts of the system update as usual. Of course eventually we'll reach some shared library that will 
end up locking up upgrades across the whole system but I can make a decision then.

The reason I ask the question is because, although I've been working with Linux since 1996 (and 
other Unices before then), I've managed to stay away from RedHat until about a couple of months ago. 
Now I'm having to learn "the RedHat way" of doing things. I may still be proven wrong but so far my 
feeling is that, frankly, if I have to contend with proprietary poorly documented incantations and 
nonexistent support and still pay for the privilege, I'd rather go to Windows Server. But I digress.

On Ubuntu, you can tell apt to simply 'hold' a package and it will just do that. Does anybody know 
of anything similar on RedHat?

Thanks

Yuri

If you are using yum to update the system, then you can add an "exclude"
directive to your /etc/yum.conf. See the man page for yum.conf.

there is a yum plugin for this purpose.

have a look:

Name       : yum-versionlock
Arch       : noarch
Version    : 1.1.16
Release    : 13.el5
Size       : 15 k
Repo       : rhel-i386-client-5
Summary    : Yum plugin to lock specified packages from being updated
License    : GPLv2+
Description: This plugin takes a set of name/versions for packages and
excludes all other versions of those packages (including optionally
following obsoletes). This allows you to protect packages from being
updated by newer versions, for example.

Best,
Hauke

Adam, thank you for this suggestion. It seems to do what I want and I'm going with it for now.

Hauke, thank you for the suggestion. I've decided to go with excludes in the conf file for now but I 
might end up using this plugin in the future depending on what happens.
