Ah, perfect! This did what I wanted. Thanks!
For the curious, I added this:
---< snip >---
#! /bin/sh
HAVELINK=$(mii-tool eth0 | grep "no link")
if [ -z "$HAVELINK" ]; then
echo eth0-link
else
echo eth0-nolink
fi
exit 0
---< snip >---
Then I set up a mapping in /etc/network/interfaces for eth0 that called that
script, as well as an iface entry for eth0-link. (I left out eth0-nolink,
which ifup just ignores with a warning.)
Thanks to everyone for their help!
