hostid is required for hostid_save and netif when /etc/rc.d/zvol is removed

[Guy Yur]

Hi,

When /etc/rc.d/zvol is removed hostid is run after
hostid_save and netif.

Attached output of:
cd /etc/rc.d
rm zvol
rcorder *


hostid is required by hostid_save in case /etc/hostid
doesn't exist so the correct hostid will be written.

hostid is required by netif for the bridge interface MAC address.
If hostid is run after netif a random MAC address will be
generated on each boot.

Attached patch against r266298 to add hostid to REQUIRE line.


Verified behavior on virtual machine installed from
FreeBSD-11.0-CURRENT-i386-20140525-r266655-disc1.iso.

/etc/rc.conf
...
cloned_interfaces="bridge0"


ifconfig bridge0 # (first boot)
bridge0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500
        ether 22:b3:11:79:51:3d

ifconfig bridge0 # (second boot)
bridge0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500
        ether 5e:dc:bd:ed:43:5d


When hostid is added to netif REQUIRE line:
dmesg -a
...
Setting hostid: 0x49d109e4.
...

ifconfig bridge0 # (on every boot)
bridge0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500
        ether 02:49:d1:09:e4:00
