Thank you Matthieu, I could compile the the zfs and opensolaris modules.


I have some additional questions:

1. I managed to create a new pool, but whenever I tried to import it,
the system stopped responding.  Did you have similar problems?

2. After the stability problems are solved, do you think it makes sense
to run ZFS on a rather low-end board?  Is it going to be usable?

3. Is there a way to enable module compilation with the crochet script?
Why is it disabled?

4. Is it better to ask such naive questions here (freebsd-arm mailing
list) or at the FreeBSD forum <http://forum.freebsd.org> in the future?
