I have a specific needs that requires yum do not to uninstall old
version when install new one. For example, I found that
yum install kernel
will install new kernel, and old kernel will remained. But
yum install <something-else>
will uninstall old version after install new one, how to disable it?
From yum.conf(5):
installonlypkgs List of package provides that should only ever be
installed, never updated. Kernels in particular fall into this category.
Defaults to kernel, kernel-bigmem, kernel-enter- prise, kernel-smp,
kernel-debug, kernel-unsupported, kernel- source, kernel-devel, kernel-PAE,
kernel-PAE-debug.
Note that because these are provides, and not just package names,
kernel-devel will also apply to kernel-debug-devel, etc.
Note that "kernel-modules" is not in this list, in RHEL-6, and so anything
providing that is updated like any other package.
installonly_limit Number of packages listed in installonlypkgs to keep
installed at the same time. Setting to 0 disables this feature. Default is
'3'. Note that this functionality used to be in the "installonlyn" plugin,
where this option was altered via tokeep. Note that as of version 3.2.24,
yum will now look in the yumdb for a installonly attribute on installed
packages. If that attribute is "keep", then they will never be removed.
