More CARP issues under 12 (maybe not CARP after all)

Yes, good point. This has worked on every other machine I have upgraded 
from 11 to 12, which is why I didnt think of that, but then all the 
motherboards are slightly different.

> Is there a reason that a standalone boot is not possible?

Sort of - I am on a serial console to do this, which works in the BIOS,
and works after the kernel has started booting, but does not work in the
loader for some reason, so I can't select single user. So I go to single
user by booting multi user and the shutting down. Of course I could use
nextboot, so its just lazyness on my part actually.

Thanks for pointing this out, I immediately jumped to the CARP 
conclusion due to last weeks experiences on the other machine,
but actually this is far more likely to be the issue.

-pete.

PS: apparently I have been playing fast and loose with this - and 
bothering the mailing list about it - since 2005... :-)

Time to change my ways I think!
