Continuing yesterday's thread: we left off with dinit launching, but /etc being messed up.
I fixed /etc! The trick ended up mounting shit on top of each other after chrooting.
Next step: make the netbsd core stuff read-only.

Also, I will slowly start publishing my current experiments. I'll call the repo fuck/fuckery.
Soo... I currently have:
- NetBSD sets mounted read-only
- Store-like, hand-made stuff mounted
- Persistence mounted
- Persistence's
/etclayered on top of NetBSD'setc dinitbooting into a system that hasgettyonconsttyforrootlogin
I basically have all the tools to make a bootable system that then I can use to develop itself. It's not there yet, because at a minimum, I need a network, and either ssh or git. Since ssh is in the NetBSD base, that's a whole lot easier.
With ssh, I can TRAMP into the system and edit the code. I can't commit locally, but I can edit things remotely, and that's good enough.
...except I don't have a user yet. Oops.
Next steps are:
- Configure the network interface
- Start dhcpcd
- Start sshd
- Mount
/varfrom persistence,unionmounted over NetBSD's/var - Set up a user for myself
- Add
git
I (well, @doctor) was also thinking about packaging and bootstrapping last night, and I think we have arrived to a plan that could make the whole distribution building a little easier!
I'll have a few special builders!
A builder for NetBSD sets: you give it a NetBSD version, a list of sets, and it downloads the binaries, and extracts them. The hash will be the NetBSD version + setlist + arch.
A builder for pkgsrc: give it a pkgsrc, $category/$program, and it builds that. Hash will be the hash of all files in the given package's pkgsrc dir.
The pkgsrc builds will not be reproducable, as they will depend on local state. They're a hack to let me bootstrap the rest of the system more easily.
This is more complicated than anticipated! Setting up the network is non-trivial work.
I might cheat there a bit.
Lets go with even smaller steps... first: adjust dinit to take care of mounting the necessary kernel filesystems like /proc, /kern, etc.
Done!
Now we'll do a bit of cheating.
Oh. I need to do the /var mounting sooner, because dhcpcd requires that.
Hrm. /etc/rc.d/dhcpcd onestart runs, but doesn't get an IP.
Aand I have network!
Uhhuh. Hm. Users will be a bit of a bother in the longer run, because the passwords are in a binary thingamajiggy. But for now, I'll shove it onto persistence.
Haha. Funny. I have no $HOME and I want to scream.
In the long run, $HOME will be tmpfs too - but not today yet.
$HOME sweet $HOME.

I could null-mount it, so it would appear as /home/algernon, but... I like it this way.
Now to set -o hidden for most of the null mounts, because...

Much better.
Next thing to fix: rebooting. Need to do the filesystem unmount dance there.
Would also need to fsck the filesystems too...
I'll also need to teach my initrd init to mount filesystems by ID, rather than /dk$N, because /dk$N is discovery ordered, and can vary between reboots.
Aha! getfsspecname(3)!
That was reasonably easy.
Ergh. Will also need a pkgin-binary builder too, for the cases where I don't want to build from pkgsrc, as a shortcut.
(This toot sponsored by sh: git: not found, and other dependencies.)
Next steps:
- Put
/etc/dinit.dunder version control - Hand-add
gitto the store - Fix reboot & shutdown
fsckall the things
And then I have a system that I can use to develop itself. Well, technically, I can do that without the last step.
Oh dear. I have Ideas™. Package management ideas.
Just spitballing here...
node carota-sativa {
operating-system netbsd
disk "/dev/ld0" partition=gpt {
// some disk partitioning stuff here
}
hostname "carota-sativa.madhouse.local"
network vioif0 { dhcp; }
service ssh {
enable
config PermitRootLogin yes
}
user algernon {
name "Gergely Nagy"
password file=${secrets.user.algernon.password}
shell package=tbd // to be decided!
}
}
Not fully fleshed out, of course. Just... spitballing here.
"But algernon, you promised us a Lisp!", I hear you all yelling.
But here's the thing I realized while I was going over a gazillion variations of configuration: one of the things I dislike about both Nix and Guix is that the configuration language and the extension language are the same.
I do not want my configuration to be a programming language. Yes, that makes some crazy stuff possible, but it also means I have to learn that language, and all its edge cases and whatnot. In case of Nix, that's a truly horrible, cursed language. In case of Guile - that's a great language! But... I still don't want to write a program as my configuration. I want it to be a document.
So I'll make it a document. A KCuddly Document Language.
But here's a twist... hold on to your pants.
