Same here. In an automated deployment situation, client changes DUID in each
phase:
- PXE (if done via IPv6)
- Installation time (from ramdisk)
- Final OS after installation
This may improve if newer versions of dhcpcd get packaged in installer ramdisks
and OS, and also for systemd-dhcp,
but I am still unaware of any implementation of machine-id as base for the
client DUID in dhclient and of course the implementations are all not exactly
the same.
And then there is still the UEFI doing the PXE part, systems with broken
machine-id etc.... And of course, dual booting if not set up with identical
cliend-DUID.
In general, my belief is that the RFC was made without real life use cases in
mind and hence did not think of these.
The patch is very helpful to overcome these issues and matches user expectation
(when specifying a MAC address in the config file, I want it to be used).
