It all depends. Some people patch nightly, but that can cause issues when the programs break due to bugs introduced in code. It is going to depend on your ability to regress or fix an issue in case of a failure.

What is your rollback time/procedure? Can you even initiate one? How do you lock which patches you need in case a machine is patched on a different day. If you point them toward the upstream distribution, chances are you will have machines with different code sets within weeks.

This is not a simple forum question like how to make sure you set NFS caching. There are entire groups at companies that handle this.

NAME
git-cherry - Find commits not merged upstream SYNOPSIS
git cherry [-v] [<upstream> [<head> [<limit>]]] DESCRIPTION
The changeset (or "diff") of each commit between the fork-point and <head> is compared against each commit between the fork-point and <upstream>. The commits are compared with their patch id, obtained from the git patch-id program. Every commit that doesn't exist in the <upstream> branch has its id (sha1) reported, prefixed by a symbol. The ones that have equivalent change already in the <upstream> branch are prefixed with a minus (-) sign, and those that only exist in the <head> branch are prefixed with a plus (+) symbol: __*__*__*__*__> <upstream> / fork-point \__+__+__-__+__+__-__+__> <head> If a <limit> has been given then the commits along the <head> branch up to and including <limit> are not reported: __*__*__*__*__> <upstream> / fork-point \__*__*__<limit>__-__+__> <head> Because git cherry compares the changeset rather than the commit id (sha1), you can use git cherry to find out if a commit you made locally has been applied <upstream> under a different commit id. For example, this will happen if you're feeding patches <upstream> via email rather than pushing or pulling commits directly. OPTIONS
-v Verbose. <upstream> Upstream branch to compare against. Defaults to the first tracked remote branch, if available. <head> Working branch; defaults to HEAD. <limit> Do not report commits up to (and including) limit. SEE ALSO
