Zeroing bspatch is correct here. This disables (well, duh!) bspatch,
and so avoids the possibility of exploiting any of the bspatch heap
overflow, etc, vulnerabilities described in
Be aware that because of the unfortunate timing of when various fixes
went into the 11.0-RELEASE sources there had been a number of people who
prematurely downloaded 11.0-RELEASE *before* the official announcement
and who therefore have not got the fixes to the latest set of security
advisories. 11.0-RELEASE was effectively re-rolled and released as
11.0-RELEASE-p1 and special care was taken so that freebsd-update(8)
could upgrade from the prematurely downloaded 11.0-RELEASE as well as
from the officially blessed 11.0-RELEASE-p1.
Remember folks, it's not been released until the fat lady sings^W^W^W
release engineer signs the announcement.
