But still I believe this to be more of a kludge than a solution: in my opinion the handbook suggests that a custom kernel should be detected and left alone. But at the same time a GENERIC kernel in /boot/GENERIC should be patched. http://www.freebsd.org/doc/handbook/updating-upgrading-freebsdupdate.html ----- However, freebsd-update will detect and update the GENERIC kernel in /boot/GENERIC (if it exists), even if it is not the current (running) kernel of the system. ----- Furthermore if I remove the kernel option from the COMPONENTS in freebsd-update.conf I think I will not get the kernel source patches anymore, right? Which in turn means I have to get them via some other mechanism, no? >From the same link as above to the handbook: ----- Unless the default configuration in /etc/freebsd-update.conf has been changed, freebsd-update will install the updated kernel sources along with the rest of the updates. ----- I think something does not add up here but I can't get my head around it (yet?).
