I followed https://docs.freebsd.org/en/books/handbook/kernelconfig/ and
compiled latest kernel with the git apply D46710.diff file

root@bsdtest:~ # uname -a
FreeBSD bsdtest 15.0-CURRENT FreeBSD 15.0-CURRENT #2
main-n272413-66fcbd9556b0-dirty: Sat Sep 21 22:43:15 UTC 2024    
root@bsdtest:/usr/obj/usr/src/amd64.amd64/sys/MYKERNEL amd64


I still get the same error though.

linux: jid 1 pid 1386 (firo-shutoff): fstatat unsupported flag 0x800


strace (linux jail) output that is relevant (same as before)

mmap(NULL, 1060864, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =

mprotect(0x802716000, 4096, PROT_READ)  = 0




maybe I am doing something wrong, no idea ¯\_(ツ)_/¯ .
