I could add that. It's probably not hard.

What's more, it has liblkid support so you could mount by label and a
few other things. It seems reasonable that you could add lvm support
as well.

The main downsides I see right now are:

- it's not in the kernel by default

- it's actually quite large beacuse i link against glibc

It's not clear these are show stoppers long term.

I think that's a different argument. Doesn't the same logic imply we
shouldn't have udevd?
