Update bootc-fetch-apply-updates.timer with comments for RandomizedDe…

[mrguitar]

…laySec=

RandomizedDelaySec= is the best kept secret of timers. Given that such few people know about it and it's very useful for large deployments, I think it makes sense to add it as a comment.

Thoughts about providing this out of the box as a comment? I'm not proposing we turn it on by default.

Hi @mrguitar. Thanks for your PR.

I'm waiting for a containers member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

👍 from me, reminds me of messing with cfengine splaytime many moons ago!

I'm in favor of turning it on by default actually...there's not really a strong downside right?

[mrguitar]

@jeckersb exactly! I always describe this as "splay"!

@cgwalters, I can't think of a downside. Maybe the comment should change to this if we enable it: "When deploying a large number of systems, it may be beneficial to increase this value to help with load on the registry."

I think 2h is a sane default, but I just put that as an example. Should it change?

[mrguitar]

ok, I tried to make that change, but since I suck at git it's stuck on DCO. :) This is what PM help looks like. lol

See https://docs.pi-hole.net/guides/github/how-to-signoff/

TL;DR do git commit --amend --signoff

[cgwalters]

I force pushed an update to this:

• squashed the commits
• Tweaked the commit message now that it's not a comment
