The newer scripts for Xen read the interface value from the vifname entry in Xenstore, so changing the name is not that critical. But this should be stabilized sooner than later. Personally, I find '_' rather ugly in an interface name... but I am open to suggestions, even fixing rc.d/network if it needs to. One could declare that ifnames must match [a-z][-a-z0-9]*[0-9], and then in /etc/rc.d/network pass them through `tr - _' before evaluating `args=\$ifconfig_$int'. This guarantees that setting ifconfig_ifN in /etc/rc.conf always works, and depends only on agreeing to the ifname policy and ensuring that all the existing ifnames actually follow it. Of course, tr might not be available yet in /etc/rc.d/network, but someone wizardlier (or more patient) with sh than I can probably work around that...
