Ash: A Gentle Primer
Also known as Dash in Debian (it's satandard POSIX shell) and sh in Busybox that sadly tainted the original BSD source file with GPL2.

what are some tiny c programs I can play about with?
Also, it's barebones POSIX, and not the Linux extensions you commonly think of. But, that means the processes are a lot simpler, and the code is often less complex. So it's a good place for a beginner to dip into to see how .e.g mv works, compared to GNU mv.

Looking for a simpler version of BusyBox for educational purposes
Sure... There are symlinks in the installation, and there's a small main() function that dispatches execution to the appropriate function based on argv[0], but that doesn't significantly impact the C implementation of each individual tool. Those seem pretty straightforward, to me. A developer reading.. e.g. chmod.c isn't going to see any evidence of symlinks, and minimal impact from the external main() function.

ISC DHCP Server has reached EOL
Ok here is my followup. I didn't go into detail about kea hooks [0] because I didn't write any kea hook before, but from what I can tell it should cover all your needs. You have to write c code which I find absurd tbh, but if it has the functionality you are looking for it could be a solution.
I already posted my dnsmasq "solution" so I will skip this. If you want a code example I could whip you one up.
Then there is coredhcp [1] and you can write plugins written in go for it.
From time to time some hobby dhcp server pop up, but most fade away since (I guess) the existing solutions are "good enough". I for instance implement a automatic provisioning and configurating dhcp setup with tftp and pxe boot using dnsmasq. It automatically creates pxe configs based on the mac address and some other stuff (tm). Kea seemed overkill for this usecase and I'm quite happy with what I got.
Your use case of automatically fixing hostnames through ISC seems a bit overkill to me as well to be frank. My home network has a few VLANs and every device in it is managed manually. It's a one time setup and most automation is unnecessary (and some devices in my network flatout ignore some dhcp options....). Aaaaanyway I still think that most dhcp servers out there support some form of scripting (heck even udhcpcd has a lease notify script that could be hacked to offer some of that functionality even though this gets only executed after the fact so a bit useless [2]).
> oh wait, I wonder how much ISC was paid … to do exactly this EOL … by these major ISPs?
I don't know. Nothing?
> Plausible future: I can envision a special DHCP vendor-specific OPTION to use time-based blockchain hash to further solidify their hold.
Reading your cynic banter I'm quite happy of not having your DHCP problems. Looking through your github repositories I can find a bunch of configuration files for dhclient, but not much in form of ISC configs (only the nintendo fix you posted in your first post). Would be really interested in your setup.

eBPF Documentary
It may become a footnote on Linux, but Linux isn't the only system out there -- and DTrace remains alive and well in many systems (not least in its reference implementation in illumos[0]).

Oxide Computer releases distribution of illumos intended to power the Oxide Rack
Nobody's paid to have it pass Open Group Unix Branding certification tests
https://www.opengroup.org/openbrand/register/
so it can't use the UNIX™ trade mark.
But it's got the AT&T Unix kernel & userland sources contained in it.

In OpenZFS and Btrfs, everyone was just guessing
> it seems like this bug might actually date back to the very beginning of ZFS with Sun
Looks like you might be right about that. The oldest commit referenced in the fix [0] was from 2006[1], which was just months after Sun released ZFS.

Grokking AVL and RAVL Trees
It could be good for in memory stores / log-structured merged trees / other data store applications although it isn't used much now-days. I find them simpler to implement and understand than red-black trees -- although that's a matter of taste I suppose. They beat red-black trees in read-heavy loads (i.e. writes / updates are more costly for AVL trees than for Red-Black trees although they beat R-B trees for read-heavy loads). You can find another implementation in Illumos (an open source Unix operating system) available here: https://github.com/illumos/illumos-gate/blob/master/usr/src/...

OpenIndiana
It's high time that the Illumos developers patched https://github.com/illumos/illumos-gate/blob/master/usr/src/... and https://github.com/illumos/illumos-gate/blob/master/usr/src/... to just set the error flag and return, and made the #ifndef TIOCSTI path in https://github.com/illumos/illumos-gate/blob/master/usr/src/... the only path.
Because by the looks of https://github.com/illumos/illumos-gate/blob/7c478bd95313f5f... the C shell was fixed years ago.

It's DragonFly BSD, not Dragon BSD, and the irony of that is that you missed FreeBSD, which is of course still going.

Linux distributions' relative popularity over time (by Distrowatch hits)
Its successor is still out there: Illumos. Though it seems to be mainly focused on backwards compatibility for existing custom applications as it still enforces things like an 8 character username limit.
