Udev rules try to rename active interfaces in some environments
Open, Requires assessmentPublicBUG


In some situations, rules from try to rename interfaces that are already in UP state what breaks those interfaces and can make others inoperable too.

Such behavior was observed when:

  1. Ethernet interface was already brought up by initrd (VyOS booted via PXE).
  2. biosdevname ( returned name not equal to what kernel assigned during boot.

It is necessary to exclude such interfaces from renaming. This can destroy an expected order of interfaces, but all of them will be kept operable.
