#33 colinux service should pass power events onto linux
Henry asked me to create a feature request to preserve
the links from an email posted to the colinux-users
mailing list on Dec 1, 2005.

[...] because I'm now using bridged networking
instead of NAT my colinux box now has to get it's dhcp
address from the external network, not from Windows
Connection Sharing.
And [ifdown/up works, but] It would just be really nice
for me if coLinux fired off an apm event when the laptop
resumed, so I can create an /etc/apm/event.d script that
gets kicked off on resume, right when I may have relocated
it onto a new network, and when I need it to get a new IP
address if necessary.
Windows does this. It wakes up and knows that it might
not be in Kansas anymore, so it sends out a dhcp renewal
request and, if it's last IP was from home, and it is now
at work, the server will offer it a new valid address and
voila: the system adapts to its new environment instantly.
But coLinux I have to kick.
It's a small thing, really. But a feature I'd really be
glad to see!
