A Cautionary Note

Note: The upstream maintainer of yum, Seth Vidal, had the following to say about ‘yum priorities’ in September 2009:

Gosh, I hope people do not set up yum priorities. There are so many things about
priorities that make me cringe all over. It could just be that it reminds me of
apt ‘pinning’ and that makes me want to hurl.
This matter was discussed in more depth in the mailing list thread starting here. The Repositories article noted in that thread, which discusses the exclude and includepkg options for yum, is a better place to start in understanding priorities.

The primary concern is that priorities is heavy handed over removing packages from the transaction set. It makes it difficult to readily determine what packages are being ignored and why. Even so, it is very flexible and can be extremely useful to provide the largest available list of packages.
