RH-Commit: [1/1] f6a5ab0e22831b67fc48afc8e80b724fcb9c8503 (vkuznets/WALinuxAgentCentOS)
|
||
|
|
|
||
|
|
This is borrowed from https://github.com/Azure/azure-vm-utils/pull/41 and
|
||
|
|
the long term plan is to get azure-vm-utils packaged for RHEL
|
||
|
|
eventually. For the time being, just put the required udev rule into
|
||
|
|
WALinuxAgent package.
