From Bugzilla Helper: User-Agent: Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en-us) AppleWebKit/312.1 (KHTML, like Gecko) Safari/312 Description of problem: ONBOOT=no is ignored on eth0:x interface aliases. If you have ifcfg-eth0 and ifcfg-eth0:0, where ifcfg-eth0:0 has ONBOOT=no set, eth0:0 is brought up anyway at boot. Version-Release number of selected component (if applicable): initscripts-7.31.18.EL-1 How reproducible: Always Steps to Reproduce: 1. Copy /etc/sysconfig/network-scripts/ifcfg-eth0 to /etc/sysconfig/network-scripts/ifcfg-eth0:0 2. Change the IP address in ifcfg-eth0:0 and set ONBOOT=no 3. Reboot machine Actual Results: Interface eth0:0 is brought up after boot. Expected Results: Interface eth0:0 should be down after boot. Additional info:
Alias interfaces are controlled by ONPARENT, not ONBOOT. This is documented in sysconfig.txt as of 7.31.11.EL-1 and later.
Oh, I see. Sorry for misunderstanding your previous note. IMHO, it may be help for busy admins to have ONBOOT also work for interface alias, rather silently ignoring it. Unfortunately I had a service outage today due to thinking that ONBOOT would work in an alias file. I didn't know to look in /usr/share/doc/ initscripts-7.31.18.EL/sysconfig.txt.
