Re: "persistent" RPMs

In my opinion, there are two scenarios:

(1) the RPM was made by you of an application you wrote yourself or is
a third party RPM of a very specific application. In this case, being
an application 'off the distribution tree', it will never be upgraded,
except when you or the authors write such an upgrade.

(2) the application is a regular application, registered as part of
the Linux distribution. In this case the chances of it not being
upgraded are slim, because most bulk upgrades will find it listed and
act accordingly. Theoretically, you could manually upgrade parts of
your distribution omitting this one package. However, it will
eventually clash with some upgrade affecting a vital library. This
could happen in case (1) above as well, except for the simplest
applications, since most use shared libraries; you could get away for
some time though, by keeping your application using static libraries.
Again, this last only with scenario (1).

The only way I have found of making software in this condition work is
by not upgrading at all. This is the reason why you find some servers
with an old distribution and they cannot be upgraded, unless they
break free from the 'untouchable' software.

Hope this is of use,
Gerardo
