Apologies if this is completely obvious to everybody, it certainly wasn't to me until now.
It seems that if a module (e.g. carp) is not started via /boot/loader.conf but in rc.conf via `kld_list="${kld_list} carp"`, then the /etc/sysctl.conf settings are not applied.
It's obvious (in hindsight) why this is - sysctl is started before kld is run:
$ rcorder /etc/rc.d/* /usr/local/etc/rc.d/* |egrep 'carp|kld|sysctl'
...
/etc/rc.d/sysctl
/etc/rc.d/kldxref
/etc/rc.d/kld
But it has caused some unexpected behaviour after rebooting, when preemption didn't work as planned.
Is this an ordering bug, or something I could improve docs for e.g. in rc.conf(5)?
A+
Dave
