Could do.

It's pretty standalone right now. You just have to run it as root as this:

# IFACE=eth0 /etc/network/if-pre-up.d/check-network-cable

The meat is, however, in the check_status() functions so they could move
elsewhere and create a script that used $1 instead.

Yep, sorry, the network-cable test in that one is still flacky, it should
reuse the code in the 'check-network-cable' script (i.e. use 'ip link show'
and look for NO-CARRIER, or use mii-tool or ethtool). I've fixed and made
available a new version up at people.debian.org (package version 0.2 now)
