Me, 4PM: "dang it, why is my incremental zfs send of /var/mysql sending the entire file instead of just the changes from yesterday???"

Me, now: "Oh. The contents of /var/mysql churn 99% between then and now."

Anyway, I'm grinding on #openzfsmastery. I'd appreciate your support. mwl.io/sponsor

Good chunk of the #openzfsmastery replication chapter done today.

But it's the last known warm day of the year, so I'm breaking several of my own rules and knocking off early to have dinner out. There's an indie bbq place with a patio I've wanted to try.

"It is possible but rare to regret having too many datasets. Far more common is wishing you had divided your data into more datasets."

Anyway, I'm working on my web server for #openzfsmastery, sites will be going up and down.

"As the old saying goes: everybody has a test environment. Some people are lucky enough to have a separate environment to run production in." #openzfsmastery #footnote

I used to call it "rubber hose cryptography" or "kneecap cryptography" or any number of things in an effort to avoid spelling out the real threat. People didn't get it.

I think I'll start calling it an "XKCD 538 attack" instead. Anyone who doesn't look it up isn't my reader. #openzfsmastery

Got the #OpenZFSMastery section on dataset-level encryption done! Tomorrow, LUKS and maybe GELI.

Really grinding to try to get a first cut of #openzfsmastery finished before my surgery. It's possible, in theory.

But taking tomorrow to chill with a buddy, watch some classic TNG, and eat pizza. Because my brain is bloody fried.

"If you cannot consistently type your passphrase correctly twice in a row, consider a simpler passphrase. If you can consistently type your passphrase correctly any number of times in a row, get a more complex one." #openzfsmastery #footnote

I'd appreciate help finishing this book. mwl.io/sponsor

Today in #openzfsmastery:

"Are you protecting your laptop from random goons or state actors? Will the impact max out at swearing, scandal, or sabotage? Is someone going to hire a character from a cheesy Lucas novel to break into your data center and steal your hard drives?"

That's chapter 10 of #openZFSmastery, on delegation, done! Covers delegating to users, #FreeBSD jails, and unprivileged #proxmox containers.

Wishing proxmox had better ZFS integration, but maybe it'll come.

But now, pajamas and Ted Lasso.

Today in #openZFSmastery:

"Lucas can now manage his own mistakes. Jude, of course, must manage the mistake of giving Lucas a jail."

I'd appreciate your support writing this book. mwl.io/sponsor

Today's #60SecondsOfWIP has escaped! "A Monstrous Heap of Redirections," from #openzfsMastery

At mwl.io/archives/25008 or wherever podcasts are sold.

My plan: writer meeting, quick grocery run, write the Patronizer post, work on #openzfsMastery.

Their plan: this.

I prefer their plan #petRats #rats

Today's #60SecondsOfWIP is out! From #OpenZFSMastery: "Lucas is Incompetent or Evil."

At mwl.io/archives/24997 or wherever mediocre podcasts are sold.

Tomorrow's #60secondsOfWIP is recorded: "Lucas is Incompetent or Evil."

Yes, that's actual text from #openZFSmastery. Written by coauthor @allanjude.com, but it's in the book.

That's why I don't have coauthors. They get to know me too well.

Got the #openzfsmastery section on privilege delegation completed.

Tomorrow, I figure out delegating datasets to containers. Seems there's little integration, everything gets delegated by hand?

Sponsorships are still open on this silly thing: mwl.io/sponsor

Me, this morning: Yay, I finished the #openzfsmastery boot environment chapter yesterday, I can move on.

Me, getting to desk and seeing the boot environment chapter: oh no.

Deep boot environments: 👎

Derp boot environments: 👍

#sysadmin #openzfsmastery

that's the Boot Environment chapter of #openzfsmastery done! Covers FreeBSD and Proxmox.

I think my Saturday's done. It's pajama time.

"While boot environments simplify recovering from bad upgrades, they can also accidentally uninstall security updates. Po-tay-to, po-tah-to." #openzfsmastery #footnote
