Subject: question on lkm / kld in 3.3-RELEASE or later
Sender: owner-freebsd-hackers@FreeBSD.ORG
Precedence: bulk
X-Loop: FreeBSD.ORG

It seems that lkm is no longer working after 3.3, it complains regardless
the mod is compiled in aout or elf (setenv OBJFORMAT before doing compiling):

# modload -ezatm_mod /lkm/znatmdrv.o
ld: /kernel: malformed input file (not rel or archive)
modload: /usr/bin/ld: return code 1

So, it looks like that kld is the way to go. However, there is no
miscellaneous module under kld (/usr/share/examples/kld/{cdev, syscall}).
Below is some comment in kld/cdev/module/cdevmod.c, It says that cdev
module is "a miscellaneous module". 

Will kld provide a miscellaneous module in the future? or miscellaneous
module is merged with cdev module?

Thanks for any information,

	-Jin
