Lost mail, sorry, I was saying ... I tried both "-t 9p" and "-t 9P".
I don't know whether or not there is a specialized mount util, as in FreeBSD. If not, IMHO, mount should recognize the available fs from /proc.9p/9P/... is not listed in /proc/filesystem, also when statically linked in the kernel. I think It should be.
