Description of problem:
When an interface is configured with ifup, the virtual interfaces attached to it (ethx:n) are also loaded despite they have ONBOOT=no configured.
This is caused by ifup-aliase NOT looking for the ONBOOT parameter.
It can be corrected by adding:
 if [ "${ONBOOT}" = "no" -o "${ONBOOT}" = "NO" ];  then
              exit 0
       fi
on the new_interface() function.

Version-Release number of selected component (if applicable):
initscripts-7.93.13

How reproducible:
Always

Steps to Reproduce:
1.ifup eth0
2.
3.
  

Actual Results:  eth0 and eth0:1 are up

Expected Results:  Only eth0 should be up (eth0:1 should also be up IF is says ONBOOT=yes, otherwise ifup eth0:1 should specified to bring up the interface)
