Description Chris Smith 2007-03-14 00:25:31 UTC
eth0 on my computer has a hardware problem that resets the machine at random.  I removed net.eth0 using rc-update, to keep eth0 down, which it must be.

However this decision is reversed by /sbin/rc.  I don't really understand the stuff with SOFTLEVEL, BOOTLEVEL, /dev/.rcboot, and so on, and I don't understand what it's doing or why, so I can't suggest a fix.

Here is a small excerpt from rc-update show -v

            net.eth0 |                               
            net.eth1 |      default                  
            net.eth2 |      default                  
              net.lo | boot                          


Reproducible: Always

Steps to Reproduce:
1. remove net.eth0 from all runlevels
2. observe that eth0 is nevertheless started up
3.

Actual Results:  
eth0 up

Expected Results:  
eth0 down

you probably have cold/hot plugging enabled in /etc/conf.d/rc
