/etc/rc.d/named dilemma

[Nerius Landys]

One last question.  I'm getting interesting [kernel?] messages during
bootup.  You know, the kind that are highlighted white in the console.

The relevant lines of rc.conf look like this right now:

defaultrouter="64.156.192.1"
hostname="daffy.nerius.com"
ifconfig_em0="inet 64.156.192.169  netmask 255.255.255.0"
waitfornetwork_enable="YES"
named_enable="YES"
sshd_enable="YES"
#ntpdate_enable="YES"
ntpd_enable="YES"
linux_enable="YES"
apache22_enable="YES"
mysql_enable="YES"


Early on in the bootup, the ifconfig shows for em0:

inet 64.156.192.169 ...
media: Ethernet autoselect
status: no carrier

Then later on:

Waiting for network to initialize.
<highlighted>em0: link state changed to UP</highlighted>
<highlighted>calcru: runtime went backwards from 37332 usec to 16577
usec for pid 47 (sh)...</highlighted>
... (more messages about calcru)

And then everything starts fine, including ntpd.

Why is em0 only brought up when I do my ping command in
/etc/rc.d/waitfornetwork?  And are these calcru messages something to
be worried about?
