Andrew (thompsa) may want to chime in and check this change for runfw
too, so I've Cc:ed him in this thread too.
This error is present for amd64 too. I just tried rebuilding a kernel
with this configuration file, and I can reproduce this error myself too:
kobe:~$ cat -nv /usr/src/sys/amd64/conf/RUNFW
1 #
2 # RUNFW -- test kernel for device runfw
3 #
4 include GENERIC
5 ident RUNFW
6
7 device firmware
8 device runfw
kobe:~$
And this is indeed the fix, because it breaks the circular dependency of
'runfw -> runfw' in sys/conf/files. Thanks!
