Hello,
I suppose there is some argument that we should support hostname.MAC
files
Maybe a function in netstart right before vifscreate could be enough to
achieve this? I creates this diff, against stable for now though, as a test.
Create a /etc/hostname.MAC file like you would create a /etc/hostname.if
file. (MAC = lladdr as shown with ifconfig. Like
/etc/hostname.08:00:27:14:26:0d)
/etc/netstart than creates a symbolic link to the corresponding
hostname.if. If there is a hostname.if file it is not overwritten. The
rest works the same.
