Works nicely. Alternative method:You could try to chroot(8) the environment and run a pkg-info(8) from there.
setenv PKG_DBDIR /mounted_fbsd_part/var/db/pkg ; pkg info
Well, technically you could load the local.sqlite database with an SQLite client and read it that way. But you would need to know how the database is structured.Not at all.
