* Installing on a drive which presents 4KiB logical sectors (a “4Kn” drive) only works with UEFI booting. This not unique to ZFS. [GRUB does not and will not work on 4Kn with legacy (BIOS) booting.](http://savannah.gnu.org/bugs/?46700)

## Support
|
||||
|
||||
If you want a supported system, see [[Debian Buster Root on ZFS]].
|
||||
|
||||
This *experimental* HOWTO uses 0.8.1-4 packages from Debian unstable, rebuilt from git. The packages are not in the Buster repository. Do not ask for support with this version of the HOWTO unless you are able to help with development.
|
||||
|
||||
If you need help, reach out to the community using the [zfs-discuss mailing list](http://list.zfsonlinux.org/mailman/listinfo/zfs-discuss) or IRC at #zfsonlinux on [freenode](https://freenode.net/). If you have a bug report or feature request related to this HOWTO, please [file a new issue](https://github.com/zfsonlinux/zfs/issues/new) and mention @rlaager.
