Oh s**t! Of course, I really should have looked to see if there's a fix for
the _underlying_ problem.

I think you're wrong but even if not, I've invested too much time in making
whereami work the way I want to want to do all this all over again with a
completely different scheme. In any case, after watching this and other
lists for years, it's clear that 'whereami' has the _best_ support from its
developer (I already have a fix from Andrew [1], thanks).

I've got no problem with a solution that doesn't prevent me using whereami -
I just don't want to get into something that requires me to completely redo
what I did for whereami.
afaict, ifplugd doesn't help, but that might be because of whereami's
action. I have ifplugd. However, ifplugd requires mii-tool, and mii-tool
requires the link to be configured (and the link isn't configured because
whereami took it down again).
Perhaps, as I suggested in my first post, all I need is to "ifconfig eth0
up" as the last step in whereami. Then ifplugd might eventually catch the
link-status change and bring up the link. However, ime, ifplugd hasn't
been doing a very good job. If ifplugd was really working, I shouldn't
even need to run whereami from the resume script - ifplugd should run it
when the link comes up. I'll look at ifplugd again, but what I've been
seeing is that it sees the link-beat, tries to bring up the interface, then
I get the b44 timeout and it takes down the interface. Eventually it's
successful but it takes quite a while. (Incidentally, I've also had
ifplugd completely freeze my laptop for somewhere around 10 minutes if I
make the mistake of removing the ethernet cable immediately _before_
shutting down the computer).
Thanks for your suggestions. I _will_ look deeper into ifplugd but I won't
be ditching whereami :-)
[1] Andrew Macmillan's solution, which doesn't appear to have been cc'd to
the list was to add the following to the whereami detect.conf:

I hadn't figured out how to force an arbitrary command to execute in the
detect script.
