If you do, then you may be interested in a tiny new tool called eclean-kernel. In simplest words, eclean-kernel could be called an old kernel harvester. Given a few tiny settings, it finds the kernels installed in the system, chooses ones to remove and removes them along with the modules and sources if not used by any other kernel. The usual way of using it is to set it to keep a few newest kernels, and remove all older than them.
To do this, you just need to pass the number as --num. For example:. For non-interactive use, omit --ask ; you can also use --pretend for eclean-kernel to list the kernel versions which would be removed. By default, it preserves all kernels referenced by the bootloader. The --destructive option can be used to disable that. If it fails to detect the correct bootloader or multiple bootloaders are installed , --bootloader option can be used to specify the one to use.

Of course you need to go through it now and again to remove apps you don't want, but the job's easier if it contains as few 'extra' packages as possible i.
List dependencies and reverse dependencies of packages, and clean the world file and the set of installed packages. Task selection: -h, -? An entry in the world file is redundant if there is another installed package that depends on it.

That happens because overlays do not contain metadata caches.
The cache is used to speed up searches and the building of dependency trees. A neat trick is to generate local metadata cache after syncing overlays. This trick also works in conjunction with eix. Use qcheck to verify installed packages:. Learn more about qcheck by reading its manual page:.
