This got me hooked. I have my sandbox "arch distro". I'm hammering it into container and pre-populate most of GNOME apps from Flatpak. And for developement enviroments I add distrobox to the core image.
I don't have anything from AUR (except bootc needs to be hooked up from there) and my command-line tools are like "20 years the same and still ongoing" type of selection for the most part :-) (e.g., I even favor regular vim over nvim).

@pid_eins Do you think this could make sense for systemd? Just poking a bit before I do decide to do anything with it.
It's derived works of https://lwn.net/Articles/723561/ with the difference that there are no container objects, there's just a new namespace. Empty root does not categorize as a FS namespace as FS namespaces are all non-empty filesystem hierarchies (enforced by BUG_ON actually).
Have been in and between whether to send this work some day or not, as anything namespaces related feature-wise are a somewhat sensitive topics to begin with...

I'm now ready to send my rootns patch set that I've had branch for some time at git.kernel.org.
I got the story now in my head why we need it (in universal sense). It has been hard to finalize the code when there is no mission to accomplish.
Now there is a mission to accomplish, which makes it easy to cover letter the code.
It's exactly Claude Mythos and similar LLM powered agentic security scanners. the window that pivot_root leaves grows too big of a risk.
We cannot rely on to stuff like this anymore.

I find rpm-ostree really cool technology. Have been playing with it my X390 Thinkpad, which is like my "testing ground for new stuff".
Has this been applied to other distributions so far similarly as in Silverblue?
I'm particularly interested could I redo this with arch baseline?

jarkkoFINALLY, figured this one out:
# Apply Linux kernel patch.
macro index L "<pipe-message>b4 shazam -l -s ''<enter>" "b4 shazam"Pay attention to ''. I don’t why it fixes everything but after hours of poking on the problem I had that by accident there and suddenly it all came together 🤷

Despite it will take still a bit of time to publish CCD, but I'll release libttk.so much sooner.
It's my retained mode single-threaded terminal UI ...
... i.e, it has jobs but they yield and multi-tasking is co-operative :-) Scenegraphs are thread-safe (or may thread-local?) in the sense that they don't shared local state.
Running fm in single-thread neither does prevent parallel processing thanks to POSIX and non-blocking I/O, and in Linux you have uring.
This is how I look at performance, when I visit the topic. I.e. not thread-bombing but only taking what you need and "stay out of the way bothering" :-)

Diseases that are contagious before people are symptomatic are especially hazardous and epidemic-prone. The epidemic is time-delayed from the initial outbreak. LLM usage begets more LLM usage, and LLM-written technical debt takes time to become symptomatic. Exponentials are harder to see from the middle.

Mind the overlapping scrollbar but looks every day more polished.
As can be figured out from screenshot, despite Ranger-alike appearance, this does not share vim-like navigation but instead has prompt always at bottom and mc-style shortcuts.
I'm a heavy vim-user myself but having less speedrun-logic in the file manager gives my brain a healthy context switch. Managing files should not be done in fast turns anyhow :-)

zpico is great: https://github.com/thornjad/zpico
And migration from zap was super easy:
# Must be set before loading `zsh-contrib/zsh-vivid`.
export=VIVID_THEME=catpuccin-mocha
export ZP_PLUGIN_HOME="${XDG_DATA_HOME:-$HOME/.local/share}/zpico/plugins"
if [ -f "$HOME/.local/lib/zpico/zpico.zsh" ]; then
source "$HOME/.local/lib/zpico/zpico.zsh"
zpico add "zap-zsh/supercharge"
fpath+=("$ZP_PLUGIN_HOME/pure")
zpico add "sindresorhus/pure"
zpico add "zsh-contrib/zsh-vivid"
zpico add "zsh-users/zsh-completions"
zpico add "zsh-users/zsh-syntax-highlighting"

I just can't use floating point numbers because we don't have them in kernel code.
Thus I implemented fixed-point arithmetic library with 16:16: and 24:8 format for my file manager ccd. It has multiplication, division, sqrt and trigonometric functions. Trigonometric functions measure in brads (binary radians) i.e., scale of 256 degrees.
