I'll keep that in mind in case I run into any future problems. Maybe
some bugs have been fixed since your last run. Another difference:
I may be able to do without v3 in the rootflags. I haven't tried
it since it's all been working, but earlier - before I had your and
Tim's help - the boot progressed just as far without v3.

Ah! No I don't. That may have been an alternative solution. Will that
tell init that there is no need to if-up eth0?
