>Description:
if root filesystem mount read-only (nfs, or etc), when machine boot I see
eval: cannot create /tmp/hostid: Read-only file system
/etc/rc: WARNING: could not store hostuuid in /tmp/hostid.
Setting hostuuid: 82559667-7d48-11de-a424-0050228da6b7.
Setting hostid: 0xbee50505.
Mounting local file systems:
========
in /etc/rc.conf file I have:
router# grep tmp /etc/rc.conf
hostid_file="/tmp/hostid"
# tmp on memory
tmpmfs="YES"
tmpsize="1m"
router#    

=======
I think, it attempt store hostid before mounting all filesystems

router# rcorder /etc/rc.d/* | grep -E "host|mount"
/etc/rc.d/hostid
/etc/rc.d/mountcritlocal
/etc/rc.d/hostname
/etc/rc.d/mountcritremote
/etc/rc.d/mountd
/etc/rc.d/mountlate
/etc/rc.d/hostapd
router#  
>How-To-Repeat:
boot with
hostid_file="/path/to/not/root/filesystems"
settings into rc.conf
>Fix:
change boot sequence?
