In fact, nobody should be setting the flags at all. I should remove them from the man page, or burry them in a footnote somewhere. So boot_mulitcons w/o boot_serial=3Dyes will mean that video is the primary console and serial the secondary, and /etc/rc only runs on the primary console.

you can give the loader a hint, which uart is considered a console.
In my case, any IPMI-console on uart1 works with the following settings in /boot/loader.conf:

--
boot_multicons=3D"yes"
comconsole_port=3D"0x2f8"

hint.uart.0.flags=3D"0x0"
hint.uart.1.flags=3D"0x10"
hint.uart.1.baud=3D"115200"
--

hint.uart.N.flags=3D"0x10" means: this is a potential system cons= ole.
See uart(4) manpage for this.

the flags at all. I should remove them from the man page, or burry the= m
in a footnote somewhere.

So boot_mulit= cons w/o boot_serial=3Dyes will mean that video is the
primary co= nsole and serial the secondary, and /etc/rc only runs on
the prim= ary console.
