freebsd-rustdate: updating FreeBSD, but a lot faster

This is freebsd-rustdate, a reimplementation of freebsd-update. It’s primarily written because of how slow freebsd-update is, and is written in rust because I felt like it.

In usage, it’s expected to be similar, but not identical to freebsd-update. There are probably a number of minor edge-case differences I don’t even know about, but there are a number of larger ones that are intentional too.

I love it when someone takes on a very well-established tool that’s used by countless people who probably barely think about how it could be improved. In this case, the performance improvements are nothing short of extraordinary, but of course, its author Matthew Fuller rightfully points out that you really shouldn’t be using this on any production system. It has not received even one percent of the kind of testing and eyeballs that the regular update tool in FreeBSD has received, so there may be edge cases or bugs.

Improving the speed of the update process is always welcome. If it’s slow and time-consuming, people might postpone the updates because they’re getting in the way of what they want to do at the moment. Sure, I doubt the average FreeBSD user is the kind of person to postpone updates and run an insecure system in the meantime, but it might still draw a few people across the line to quickly get them done before continuing their work.

This new rust-based FreeBSD update tool is definitely not going to be replacing the current one any time soon, nor is it even a part of the FreeBSD project in the first place, so there’s no need to worry about any potential breakage to your FreeBSD system because they’re replacing a battle-tested tool with a new one. All this does for now is highlight that there’s gains to be made here, and that’s a goal worth pursuing.
