A live tree of systemd jobs on the boot console direct repository linkDebated

The discussion centers on a visualization tool for systemd boot jobs, which serves as a catalyst for a broader debate regarding systemd's monolithic architecture versus simpler alternatives like OpenRC or Runit. Participants strongly disagree on whether systemd's complexity and aggressive integration are necessary modernizations or detrimental violations of the Unix philosophy that hinder debugging and flexibility.

> Just like cheap plastics and improved processes has enabled us to rapidly manufacture anything we want for a very low price Have they? Most of the world production is tied down to expensive factories and machines. Yes, we have more products, but that the result of the global trade, which is a very complex system. > Produce it cheaply and if it breaks throws it away and reproduce it. I don't know why everyone would ever wants this. It's been parroted since forever, but the true usefulness of software is to be able to build it once and runs it indefinitely. If some edge case occurs, I fix it. Which is way cheaper than rebuilding the whole thing. The goal is to have something like OpenBSD's ed[0] or dmesg[1], which you only touch every few years or so [0] https://github.com/openbsd/src/commits/master/bin/ed [1] https://github.com/openbsd/s

As I mentioned in the post, I only did a brief exploration of OpenBSD in order to cheer myself up. I took some findings, confirmed them being true bugs, and ended there. As I said in the out of bounds null termination write patch, I don't believe it's exploitable. I would have gotten a CVE, website, and logo then (kidding!). But it was UB. And one-byte overflows have in the past been exploitable by better sploit authors than me. In any case, I reported that since I felt it was clear that OpenBSD folks would obviously care about it, exploitable or not. Confirming these findings take time, even though I found GPT to almost always be correct. I will NOT report upstream until I understand the bug. I ain't no slop reporter. As I said in the post OpenBSD (and all other code bases) need a larger effort. The Mythos/Glasswing effort focusing on ac

tually exploitable ones may be a good method for getting them fixed, without overwhelming projects with patches, even when the patches are correct. I did confirm at least one more UB, and did consider whether to report that OpenBSD `find` reads `status` via `WIFEXITED(status)` without checking `waitpid()` for errors. This is UB since `status` is uninitialized. (https://github.com/openbsd/src/blob/ae684bfaed6cae797cd90e27...) The reason is my previous experience with OpenBSD where the reply may be "<some standard> is wrong in this regard", and because they control their whole system, they don't care. E.g. in this case they may go "we build with GCC x.y.z exactly, and we know what actually happens in this controlled domain". This may be a bit unfair to them, but not by much. GPT also flagged the extremely surprising behavior of running `cat -n file1 file2` if file1 doesn't end with a newline. And that `find /etc/passwd -execdir[…]` doesn't run the command. But maybe that's how they want it? I don't want to go through the whole thing for them to go "yeah we won't do that" again. So I think this project is for them. GPT is as available to them as it is to me. Tangent: in running GPT against `cat` I learned that not only is `cat -n` not standardized, but it also behaves COMPLETELY differently than on Linux, if you provide more than one file.
