Hi all,
Just to tidy up my previous emails about the patch for net boot on bridge and
vlan.
I made the patch for system to boot off network on a vlan or using a bridge
network.
To use vlan for net boot, you need to specify vlan and ip kernel options for
the boot interface. For example,
vlan=eth1.1:eth1 bootdev=eth1.1
ip=1.2.3.4:1.2.3.4::255.255.255.0:my-hostname:eth1:none
To use bridge for net boot, you need to specify bridge and ip kernel option for
the boot interface. For example
bridge=br1:eth1 bootdev=br1
ip=1.2.3.4:1.2.3.4::255.255.255.0:my-hostname:eth1:none
In my environment, I needs to boot machines from network within a vlan or on a
bridged network.
I found curent dracut release if-up.sh script in 40network module bypass ip
setting for both bridge and vlan interface.
Please see the patch I created. And please let me know if I need to tidy it up
a bit more or
add additional code to handle ip settings for bridge and vlan.
