I don't understand why anyone would want fsck for Btrfs or ZFS. The
designs of the filesystems make traditional fsck unnecessary.

I also don't see what's "scarey" about it.

My experience is that Btrfs is stable for day to day use, and SuSE
agree: it's their default filesystem for the OS volumes on SLES. Data
volumes on SLES are XFS because random access databases don't work so
good on COW storage.

Regarding ZFS licensing: the only "problem" with distributing ZFS
modules is a (probably well-meaning) misuse of the terms "derivative
work" and "combine". ZFS clearly is not derivative of the Linux kernel
and loading a kernel module does not in and of itself constitute
"combining" software.
