I notice that sysctl -d doesn't work, and I suspect it never did.
Looking at the code, sbin/sysctl/sysctl.c uses MIB {0,5} to request
the description of a variable, but the code in sys/kern/kern_sysctl.c
only supports {0,0} through {0,4}. Additionally, the macro SYSCTL_OID
doesn't reference the description string.
I recall some months ago, there was a discussion about the description
strings, but I don't think it went anywhere.
My feeling is that the description strings should be put into an ELF
segment which isn't loaded - sysctl(3) would return an offset into
that segment and it would be up to the caller to extract the string
from the relevent section of kern.bootfile. I know this is all
relatively easy, but my system seems to be missing elf(5) :-), so I'm
not sure of the details.
kern_sysctl.c also states:
* This interface is under work and consideration, and should probably
* be killed with a big axe by the first person who can find the time.
Is anyone actually working on this?
Peter
