The US (and the rest of NATO) is being cautious for a reason, and it's not because they're using Ukrainians as "meat shields."
NATO stocks of war materiel were at historically low levels before February 2022, and it's difficult for the US to commit fully when China is sabre-rattling over Taiwan. That's Xi's (and Kim Jong-Un's, to a lesser extent) gift to Putin. Sabre-rattling keeps the US from engaging fully in Ukraine, even though China won't be ready to invade Taiwan for several years yet.
Unfortunately for Ukraine, it'll be several years before NATO materiel stocks start to grow above 2022 levels, but they will grow.
The question is, will they grow fast enough?
Personally I'm predicting world war in 2027-28 unless the West pulls its finger out.
Do we have to bring this up again? It's just boring.
systemd is here and it isn't going anywhere soon. It's an improvement over SysV, but the core init system is arguably less well-designed than some of the other options that were on the table 10 years ago when its adoption started. The systemd userspace ecosystem has significantly stifled development of alternatives that provide equivalent functionality, which has led to less experimentation and innovation in those areas. In many cases those systemd add-on services provide less functionality than what they have replaced, but are adopted simply because they are part of the systemd ecosystem. The core unit file format is verbose and somewhat awkward, and the *ctl utilities are messy and sometimes unfriendly.
Like most Red Hat-originated software written in the last 15 years, it valiantly attempts to solve real problems with Linux, and mostly achieves that, but there are enough corner cases and short-sighted design decisions that it ends up being mediocre and somewhat annoying.
Personally I hope that someone comes along and takes the lessons learned and rewrites it, much like Pulseaudio has been replaced by Pipewire. Perhaps if someone decides it needs rewriting in Rust?
