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

"If you need to use BIOS booting with ZFSBootMenu, check the project documentation. I'm not going through it because I live in 2026." #openzfsmastery #nonotryagain

I should probably put a link to the book sponsor page, but promoting #twistedPresents has devoured my promo spoons.

TFW you install a new boot loader on a linux VM and reboot but the FreeBSD virtualization host disappears seconds later so you think you installed the loader on the wrong host, but it turns out that the robovac unplugged the server right then. #sysadmin

Anyway, #openzfsmastery is going swimmingly.

Preparing for battle ZFS boot environments on Proxmox for #openzfsmastery.

Working on #openzfsmastery, trying to fake boot environments with Proxmox. Because Proxmox integrates ZFS as a first-class filesystem.

It's going swimmingly.

Today's #60SecondsOfWIP is out! "The New Linker Strangles," from #OpenZFSmastery

mwl.io/archives/24982

"In Linux, running ZFS-on-root is an advanced skill.¹

¹ You can tell it's an advanced skill by the way senior sysadmins say, 'oh, it's not that hard.'"

#openzfsmastery #sysadmin

Me: I seriously need to work on the #openzfsmastery manuscript today.

Also me: does an hour of #skybreach revision, finalizes the #TwistedPresents Kickstarter, documents setting crowdfunding costs and prices, and slams together an outline for the long-awaited "How I Make a Living #Writing" book.

Thanks to USPS price increases, I will be increasing the cost of #openzfsmastery sponsorships this week.

Grab now if you want them cheap.
