...I don't believe it...
I ssh'd all the time to the gateways and never had a look to the
bootmessages
2x "ifconfig invalid argument" was the hint at boot.
The fault (syntax typo?) was included in hostname.carp[0,1] -
"\" for a 2-liner didn't work... despite the usage of blanks only.
Crunched it to a 1-liner and all worked...
Seems that the parsing is different at booting?

Hello @list,
perhaps I'm stupid but I've got a problem with two CARPed gateways
running 5.7-amd64 stable.
Hardware:
two supermicro-board machines with four network interfaces each (em0 ..
em3).
Networks:
LAN A : 172.16.210/24 via em0
LAN B : 172.16.0/24 via em1
direct connect for pfsync: 1.1.1.0/30 via em3
Gateway A setup --- (master) ---
hostname.em0:
"inet 172.16.210.2 255.255.255.0"

hostname.pfsync0
"up syncdev em3 syncpeer 1.1.1.2"
sysctl net.inet.carp ->
net.inet.carp.allow=1
net.inet.carp.preempt=1
net.inet.carp.log=7 #debugging

problem description --
(remark: failover-switching works on both machines in both directions)
If one of the machines reboots, the local carp-interfaces stuck in
"INIT" state. Same behavior on both systems.
The log (A) after reboot:
carp: carp0 demoted group carp by -1 to 162 (carpdev)
carp: carp1 demoted group carp by -1 to 161 (carpdev)
carp: pfsync0 demoted group carp by -1 to 32 (pfsync bulk done)
carp: pfsync0 demoted group pfsync by -1 to 32 (pfsync bulk done)
carp: pfsync0 demoted group carp by -32 to 0 (pfsync init)
carp: pfsync0 demoted group pfsync by -32 to 0 (pfsync init)
If the carp-interfaces are subsequently restartet via netstart command,
all works like a charm again...
The log (A) after "sh /etc/netstart [carp0,carp1]":
carp0: state transition: INIT -> BACKUP
state transition: BACKUP -> MASTER
state transition: INIT -> BACKUP
state transition: BACKUP -> MASTER
No PF-ruleset-problem!
resulting question -
what the heck is going on here? ;-)
alternative: what did I forgot to configure?
Thanks for reading...
