/etc/ppt_aliases needs to be in the boot archive
12680 added PCI pass-through support in bhyve and introduces a new driver aliases file called
This file needs to be added to the boot archive so it is available during early boot.
This was done in OmniOS under https://github.com/omniosorg/illumos-omnios/commit/84bf4029fafd4fe7f1a2afd13999f

I kinda doubt that /etc/ppt_aliases if of any use outside of SmartOS. It's really just a kludge to work around the problem that changes to /etc/driver_aliases aren't persistent across reboots in SmartOS, hence we introduced this new file which to be loaded as a module by the bootloader.
In any other illumos distribution it's probably much easier and less confusing to just use the normal driver_aliases mechanism, using update_drv(1M) to attach ppt to a device.

I have been using
ppt_aliases up to now just because of the problem that John highlights - I wanted to keep the original mapping in the
driver_aliases and keep
pkg verify happy:
