Thank you for your rapid reply, Baptiste!
No. This is UFS2 only -- no nfs, no zfs.
I'll send you a copy of the pkg.sql.xz directly.
I did notice that when I used the sqlite3 cli, that the database was
created, and that the size looked correct. But issuing pkg info
resulted in many SQL related errors.

Anyway. I'll send you the file.

Thanks, again.
