Description
This test case tests if /etc/udev/rules.d/70-persistent-net.rules of an existing install is honoured or not.
Setup
Install Fedora 14 on your system.
How to test
1. Verify /etc/udev/rules.d/70-persistent-net.rules exists and has the current names captured. For ex:
This file was automatically generated by the /lib/udev/write_net_rules
program, run by the persistent-net-generator.rules rules file.
You can modify it, as long as you keep each rule on a single
line, and change only the value of the NAME= key.
# PCI device 0x14e4:0x1639 (bnx2) (custom name provided by external tool)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:21:9b:9d:a5:76", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth3"
# PCI device 0x14e4:0x1639 (bnx2) (custom name provided by external tool)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:21:9b:9d:a5:70", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
# PCI device 0x8086:0x10c9 (igb) (custom name provided by external tool)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:1b:21:54:33:3c", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth4"
All the interface names can be seen by
[root@fedora14-r610 rules.d]# ls /sys/class/net/ eth0 eth1 eth2 eth3 eth4 eth5 lo
2. Upgrade to Fedora Rawhide Rawhide and boot into Rawhide.
3. Once in Rawhide, verify that the file /etc/udev/rules.d/70-persistent-net.rules exists and names as defined in it are retained.
All the interface names can be seen by
[root@rawhide-r610 rules.d]# ls /sys/class/net/ eth0 eth1 eth2 eth3 eth4 eth5 lo
Expected Results
Network interface names in Fedora Rawhide should be the same as they were in Fedora 14.
