The startup scripts insist on trying to load a module (50
times) for each atboot network interface. This includes the
loopback interface, which doesn't even seem to be allowed to
be a module, as well as interfaces which may be compiled
statically into the kernel. It fails slowly but gracefully.
You compiled your own kernel without IP aliasing, correct?
Comment out the section of /etc/sysconfig/network-scripts/ifup-aliases
that pertains to linuxconf; its IP-alias support is, interesting.
This is already done in the latest initscripts in Raw Hide.
