So at least on debian-based systems, mounting by UUID or label is actually handled in userspace by libblkid from util-linux.
If you want to try it out, I have a prototype version of util-linux with bcachefs support

I made a little tool to solve exactly this problem: https://github.com/yshui/bcachefs-mount
Cool! And it's in Rust, lovely.
I'd love to pull this into bcachefs-tools - and I'd love to use Rust for more userspace code, so I'm happy to add the Rust dependency. Would you like to merge this into the bcachefs-toos repo, so I can pull it in?
If you call it mount.bcachefs, mount(8) should call it automatically.

@modelrockettier @koverstreet How do I mount a bcachefs disk group (foreground and background) with /etc/fstab, so grub can pick it up accordingly? Please see my reddit post here.

This is how my fstab looks like. I really dont know how to handle a bcachefs disk group in fstab.

any news on this?
it would be nice to have something like that, because its a mess if you use bcachefs with many disks (I've other setups with 120disks)

I see a lot of commits on this issue, is it possible yet? Any update you could give us?

@RlndVt All this commits are linked here because they contains the string #1 in their commit message, but they are all irrelevant. I think it's better to move this issue to bcachefs-tools
Edit: Ah, bcachefs-tools repo doesn't take issues. Maybe close this and reopen? @piedar

Would you like to merge this into the bcachefs-toos repo, so I can pull it in?
I would love to. But I am not sure how the build systems would fit together.
If you call it mount.bcachefs, mount(8) should call it automatically.
This tool doesn't take the usual mount options. I intend to make it more mount(8) compatible, but it would take some time.

Having the makefile call cargo build for the mount.bcachefs target should work fine.
I'd like to get this merged in, we can continue to make improvements.
