Ahh, so I was being dense.... sysctl never crossed my mind.

I've added sysctl debug.bootverbose=1 to /etc/sysctl.conf and rebooted.
The reboot completed without complaints about errt, but as it came up
multiuser the console reported:
sysctl: unknown oid 'sysctl debug.bootverbose' at line 11

However, if I type 
sysctl debug.bootverbose=1 while logged in as root I see
root@pelorus:~ # sysctl debug.bootverbose=1
debug.bootverbose: 0 -> 1
root@pelorus:~ #

So, for some reason the command has to be entered interactively,
at least for now.

Rebooting with shutdown -r reported swap device removal.
The errt complaint remained absent.

There's something odd about sysctl debug.bootverbose. For example:

root@pelorus:~ # sysctl -a | grep -i bootverbose
<118>sysctl: unknown oid 'sysctl debug.bootverbose' at line 11
debug.bootverbose: 0
root@pelorus:~ # sysctl debug.bootverbose
debug.bootverbose: 0
root@pelorus:~ # sysctl debug.bootverbose=1
debug.bootverbose: 0 -> 1
root@pelorus:~ # 

Am I committing some invisible (to me) typo?

Thanks for writing!
