When debug.verbose_sysinit=1 is set in loader.conf(5), is normal to _not_
have BOOT and copyright messages?

It's normal (in that situation) to require a higher value in
kern.msgbufsize if you want the entire dmesg output saved in
/var/run/dmesg.boot, yes.

I use a shell script to modify that (in /boot/loader.conf.d/) in
conjunction with requesting a "verbose" (or not) boot.

E.g., on my laptop, the default value is 98304, which is fine for a
"normal" boot; for a "verbose" boot, I set it to 196608 (which works in
this case).

Thanks. 196608 was enough for me.
