Bcachefs is not very stable right now,
Neither is Spectrum! Given that changing filesystem later if it doesn't work out will be a very easy change to make (up to a point), we can afford to wait. It's an approach that has served us well so far — sometimes focusing on other things means that by the time we have to look at something, the problem has been solved by somebody else.
Filesystems are always going to have bugs, so in my opinion the most important thing is to make having good backups easy, so that recovery is possible when something goes wrong, regardless of choice of filesystem. I am very keen for Spectrum to have an integrated backup solution, ideally as easy to use as Time Machine.
To clarify, I'm not referring to bugs that cause data loss, but to bugs that allow kernel code execution when a maliciously crafted filesystem is mounted. Backups don't protect against this. This attack is mostly relevant for kiosks, mobile devices, and other cases where being able to restore trust after a device compromise is critical.
So are you saying that bcachefs's lack of stability means that it's uniquely vulnerable to this sort of vulnerability? I'd be surprised, given that as you say Kent is actually interested in preventing them.
