Description David Gilbert 2017-06-13 19:50:59 UTC 
I found this bug because my jails use a jailname.fstab to use nullfs to mount some things (ports, home directories, etc) inside the jail.

From the 11.0 to new copy of stable, this brakes.  To test, I did "cd /usr/src/sys/modeules/nullfs" followed by "make all && make install".  Then:

after "kldload /boot/modules/nullfs.ko", dmesg had:

KLD nullfs.ko: depends on kernel - not available or version mismatch
linker_load_file: Unsupported file type

Then, just to be sure:

[1:11:311]root@vr:/usr/src/sys/modules/nullfs> file /boot/modules/nullfs.ko
/boot/modules/nullfs.ko: ELF 64-bit LSB relocatable, x86-64, version 1 (FreeBSD), not stripped

Your expecting to be able to load an 11.1 kernel module on 11.0 kernel?

This is expected behavior as far as I can see, you need to build, install
and reboot to a new kernel in order to be able to run new modules.

(In reply to Rodney W. Grimes from comment #1)

No.  To be specific.  Without changing sources, I tried rebuilding a module in case it was bad/corrupt.

But the kernel won't load nullfs.  I've remade the whole kernel with make buildkernel/installkernel.

Urgh.  Bitten by boot environments.
