I am actively using planport on FreeBSD14. So far, I found  some programs which do not work: These are some servers, where threadmaybackground() should be included, vacfs vnfs (as I reported under issues on plan9port github).

9pfuse also is not expected to be usable, as the fusekernel and the supplied fuse.h don't match.
If you need it,  give me a note to get the patch.
9pfs is a better alternative in most cases.

Overall, what works at all, mostly works reliably.
