FreeNAS Corral has let the docker genie out of the bottle,  but I share your reservations about embedding Linux tech in a FreeNAS install.  If the presence of docker detracts from and belittles the use of jails, I see that as a negative.  But then, I don't need a NAS stuffed with apps.  I'd like to see FreeNAS promote and exploit the strengths of FreeBSD.  I believe they are to adopt the latest version of iocage.
