Ask HN: Those making $0/month or less on side projects – Show and tell
RoQR: https://roqr.app/
It's a privacy-focused dynamic QR code application. Just got my first paying customer this past week, which I'm pretty stoked about!
The costs of running it are very low (~$15 / month), and it's not something I'm planning on ever turning into my main gig, but the fact that someone is willing to pay for an app I built on my own feels really fun

Show HN: I built RoQR, a privacy-respecting platform for dynamic QR codes
[RoQR is open-source](https://github.com/roqr/roqr), licensed under the AGPL.
If you’re interested, I have a [longer post](https://roqr.app/blog/introducing-roqr/) on our blog announcing the launch. Happy to answer any questions and would love to hear any feedback you might have.

Bash Debugging
We use a couple nice home-grown functions in ZFSBootMenu to help debug things. We have a zdebug logging function that's peppered liberally throughout the code base - https://github.com/zbm-dev/zfsbootmenu/blob/master/zfsbootme...
Hitting ctrl-t on our main menu will, when booting with debug logging enabled, show a screen like this: https://imgur.com/Ge75zkP
We also have a flamegraph profiling mechanism that can be enabled with https://github.com/zbm-dev/zfsbootmenu/blob/master/zfsbootme... . That will dump data to a serial port, which when re-assembled, can be used to produce a graph like https://raw.githubusercontent.com/zbm-dev/zfsbootmenu/master...
Bash is suprisingly flexible.

Pure Bash Bible
A lot of what's in the Pure Bash Bible is horrifically slow. Many of those things are substantially faster, even when paying the cost of starting a new process, when you use an external and commonly available tool. I wrote a bash performance profiler that outputs data in a format that flamegraph.pl recognizes - it really helped identify where we could improve the performance of ZFSBootMenu.
https://github.com/zbm-dev/zfsbootmenu/releases/tag/v1.12.0
Don't fall in the trap of thinking things have to be written entirely in bash; it's okay to use other tools to help fill in the gaps.

Some preinstalled options/defaults suggestion
If instead of "opensuse" you're asking for bootloader as grub can't boot from zfs, then, like i metnioned, i don't use grub2, i uninstalled it, instead i'm using https://github.com/zbm-dev/zfsbootmenu

ZFSBootMenu how to increase font resolution?
I thought the following was supposed to fix this issue: https://github.com/zbm-dev/zfsbootmenu/commit/84da18e64ebcc0c483e7b2c7d3972f7d91784e63

How do I configure the refind.conf and refind_linux.conf (and or config.yaml (for ZFSBootMenu)) files properly when installing Arch Linux with ZFS Native Encryption?
All release assets, including EFI executables and kernel/initramfs pairs, are signed with signify, which provides a simple method for verifying that the contents of the file are as this project intended. Once you've installed signify (that's left as an exercise, although Void Linux provides the signify package for this purpose), just download the desired assets from the ZFSBootMenu release page, download the file sha256.sig alongside it, and run:

How to keep Ubuntu from creating a dozen /var subdirectories?
I think the consensus is that you probably shouldn't be installing a ZFS on root using the native installer anymore. They aren't really maintaining the packages that make that work. Instead the suggestion is to go the zfsbootmenu route of installing.

Cloned my root dataset and now it won't boot because NTP daemon can't reach time servers
Glad to hear that everything is working for you! I've opened a PR that adds a warning about this condition - it should likely make it into 2.2.0.

Ubuntu 23.04 Desktop's New Installer Set To Ship Without OpenZFS Install Support
You can install following instructions at https://openzfs.github.io/openzfs-docs/Getting%20Started/Debian/Debian%20Bullseye%20Root%20on%20ZFS.html which I've automated with https://github.com/HankB/Linux_ZFS_Root/tree/master/Debian. For scripting, you should also look at https://github.com/zbm-dev/zfsbootmenu. I'd probably go that way if I were starting from scratch.

Void Linux and root-on-ZFS question
ZBM provides an amazingly useful script in it's wiki here. This runs when a new kernel is updated by xbps and it snapshots your system before the kernel is installed. This creates a boot environment, and via the magic of ZFS boot environments, allows you to rollback any kernel update to a known, working configuration.

When root on ZFS breaks on Arch Linux
* https://docs.oracle.com/cd/E86824_01/html/E54764/beadm-1m.ht...
> A ZFS boot environment is a bootable clone of the datasets needed to boot the operating system. Creating a BE before performing an upgrade provides a low-cost safeguard: if there is a problem with the update, the system can be rebooted back to the point in time before the upgrade.
* https://klarasystems.com/articles/managing-boot-environments...
Or perhaps:
> In essence, ZFSBootMenu is a small, self-contained Linux system that knows how to find other Linux kernels and initramfs images within ZFS filesystems. When a suitable kernel and initramfs are identified (either through an automatic process or direct user selection), ZFSBootMenu launches that kernel using the kexec command.
