Please review the attached patch to fix the sysctl interface to accept
data of zero length. This fixes the case where one wants to clear a
string exported via sysctl, as in:
sysctl kern.hostname=
Right now, the above will do nothing. With this patch, it will clear
(i.e., set to "") "kern.hostname".
About time, too! Hope this one gets committed soon :)
FWIW, I've been running it here for a couple of months (ever since it
came up back in January), and there have been no adverse effects
of setting string sysctl's to empty strings.
G'luck,
